Abstract
An electrode includes a living body contact portion that is to be in contact with a living body and that contains a rubber material and at least one carbon material selected from carbon nanotubes and graphene. The ratio of the volume resistivity of the living body contact portion to the surface resistivity of the living body contact portion is 1.2 or more. The amount of the carbon material in the living body contact portion is 3 parts by mass or more and 20 parts by mass or less relative to 100 parts by mass of the rubber material, or the living body contact portion has a 25% compression hardness of 20 kPa or more and 110 kPa or less.
