The following describes a power supply unit for an aerosol generating apparatus, which is one embodiment of the present invention. First, the aerosol generating apparatus equipped with this power supply unit will be described with reference to Figures 1 to 8. (Aerosol generating device) The aerosol generator 200 is a device for generating an aerosol with added flavor without combustion and for inhaling the generated aerosol. The aerosol generator 200 is preferably small enough to fit in the hand, and for example, as shown in Figures 1 and 2, it has a rounded, roughly rectangular parallelepiped shape. However, the shape of the aerosol generator 200 is not limited to this, and it may be rod-shaped, egg-shaped, etc. In the following description, of the three orthogonal directions in the aerosol generator 200, they will be referred to as the up-down direction, the front-back direction, and the left-right direction, in order of length. Also, for convenience, in the following description, as shown in Figures 1 to 8, the forward, backward, left, right, upward, and downward directions will be defined as Fr, Rr, L, R, U, and D. Referring also to Figure 3, the aerosol generator 200 comprises a power supply unit 100, a first cartridge 110, and a second cartridge 120. The first cartridge 110 and the second cartridge 120 are detachable from the power supply unit 100. In other words, the first cartridge 110 and the second cartridge 120 are interchangeable. (Power supply unit) The power supply unit 100 comprises an internal unit 2A and a case 3a, with at least a portion of the internal unit 2A housed in the case 3a. Case 3a consists of a first case 3A and a second case 3B that are detachable in the left-right direction (thickness direction). The front, rear, left, and right sides of the power supply unit 100 are formed by assembling the first case 3A and the second case 3B in the left-right direction (thickness direction). Specifically, the first case 3A is supported on the left side of the chassis 50 (described later) included in the internal unit 2A, and the second case 3B is supported on the right side of the chassis 50, housing the internal unit 2A in case 3. A capsule holder 4A is provided on the upper surface of the power supply unit 100, facing forward. The capsule holder 4A has an opening 4a that opens upward. The capsule holder 4A is configured so that the second cartridge 120 can be inserted through the opening 4a. A mouthpiece 130 is detachably attached to the second cartridge 120. The upper surface of the power supply unit 100 is formed by an OLED (Organic Light-Emitting Diode) cover 5a located behind the opening 4a, and the lower surface of the power supply unit 100 is formed by a lower cover 8a on which the charging terminal 1 is provided and a rotatable lower lid 7a.
