A bioelectrode includes a fitting member (1106) formed by an electrically insulating member fixed on a surface of a garment (1100) that comes in contact with a living body (1000), an electrode part (1101a) formed by a conductive member fixed on a surface of the fitting member (1106) that comes in contact with the living body (1000), a connector (1102a) fixed to the fitting member (1106) and configured to connect a bioelectric signal measurement device, a wiring line (1103a) fixed to the fitting member (1106) and configured to electrically connect the connector (1102a) and the electrode part (1101a), and an electrically-insulating insulating member (1105) configured to cover a portion within the surface of the wiring line (1103a) that comes in contact with the living body (1000).
