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.本發明提出一種不會對受檢者強加過大負擔而可提高檢測精度之生物訊號檢測用裝具。本發明之生物訊號檢測用裝具係用於檢測頭部之生物訊號者,其包含可支持頭部之支持體及設置於支持體上之電極。電極包含複數個齒,該等齒包含使1對導電性之線材形成為環狀之環狀部分、與使該1對線材於相反方向捲繞而形成為棒狀之棒狀部分,複數個齒中之棒狀部分之一端係對支持體直接或間接地固定。12A...齒部12B...齒支持棒
