PROBLEM TO BE SOLVED: To provide a brain wave measuring electrode capable of sufficiently securing conduction by being brought into contact with a scalp without using conductive paste and reducing the burden of a subject.SOLUTION: A brain wave measuring electrode 10 including a base material 12 which is formed by an elastic body, and a structure formed on the surface of the base material. The base material 12 includes projection parts 12b having a contact surface 12c to be brought into contact with a scalp, and the structure includes a plurality of nanocarbon materials, forms a network structure in which the plurality of nanocarbon materials are mutually connected, and is fixed to the surface of the base material 12.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】導電性ペーストを用いずに頭皮と接触して導通を十分に確保でき、しかも、被験者の負担を軽減できる脳波測定用電極を提供する。【解決手段】弾性体からなる母材12と、前記母材の表面に形成された構造体とを備える脳波測定用電極10であって、前記母材12は、頭皮に接触する接触面12cを有する突出部12bを備え、前記構造体は、複数のナノ炭素材料を含み、前記複数のナノ炭素材料が、互いに接続されたネットワーク構造を形成していると共に、前記母材12の表面に固定されていることを特徴とする。【選択図】図1
