Abstract: A bioelectrode includes an electrode portion that acquires an electric signal of a living body or outputs an electric signal to the living body. The electrode portion is provided with an electrolyte layer that is in close contact with the living body, and is also provided with a sheet-like cover member that covers at least a part or all of the electrolyte layer. The cover member being provided with an opening that penetrates in a thickness direction, thereby discharging moisture accumulated in the electrolyte layer and preventing the swelling and deterioration.

Abstract: The object of the invention is to provide a biomedical electrode which enables a user to easily attach by oneself without making any mistake with no specialized knowledge being required.
