Abstract

A biosignal measurement device is proposed which can improve measurement accuracy without forcing an excessive burden on subjects.A biosignal measurement device used for measurement of a biosignal in a head includes a support that can support the head, and an electrode provided to the support. The electrode has a plurality of teeth each including an annular portion in which a pair of linear members having conductivity are formed in an annular shape, and a rod-like portion in which the pair of linear members are wound in opposite directions and formed in a rod-like shape. The rod-like portion in each of the plurality of teeth is directly or indirectly fixed at one end to the support.
