Description

TECHNICAL FIELD The present invention relates to an electroencephalogram measurement device. BACKGROUND ART In electroencephalogram measurement, electrodes are placed on a head to conduct electrical measurements. Patent Document 1 discloses a probe for electroencephalogram measurement, in which a tip capable of allowing an electrolytic solution to bleed out is brought into contact with a skin of the head. RELATED DOCUMENT PATENT DOCUMENT [Patent Document 1] Japanese Unexamined Patent Publication No. H1-236036 SUMMARY OF THE INVENTION TECHNICAL PROBLEM However, in the technique disclosed in Patent Document 1, since a half cell is configured by the electrode and the electrolytic solution in the tip for performing the measurement, the structure of the probe is complicated. The present invention provides a simple electroencephalogram measurement device capable of supplying a liquid to a scalp and performing measurement. SOLUTION TO PROBLEM According to one aspect of the present invention, the following electroencephalogram measurement device is provided. 1. An electroencephalogram measurement device including: a support which is mountable on a head;an electroencephalogram electrode member which is held by the support; anda tube which passes through a through hole provided in the electroencephalogram electrode member.2. The electroencephalogram measurement device according to 1., in which the electroencephalogram electrode member includes a base and one or more protruding portions provided in the base, andthe through hole is provided in the base.3. The electroencephalogram measurement device according to 2., in which the tube penetrates the base.4. The electroencephalogram measurement device according to 3., in which a protrusion height of the tube from the base is smaller than a protrusion height of the protruding portion from the base.5. The electroencephalogram measurement device according to any one of 1. to 4., in which the tube is insertable into and removable from the through hole of the electroencephalogram electrode member.6. The electroencephalogram measurement device according to any one of 1. to 5., further including: an injection member for injecting a liquid into the tube.
