Bioelectrode

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. This object can be solved by a biomedical electrode used for transmitting electrostimulation to a biomedical electrode used for transmitting electric stimulations to a biological body, for sensing electric signals from a biological body, or for both, by contacting said biomedical electrode to the biological body, in which said biomedical electrode comprises: a base materialformed into a sheet-shape; electrode partsprovided on any one surface of said base material; electrolyte layerscovering said electrode parts; terminal partsexposed on the opposite surface to the surface on which said electrode partsare provided, being electrically connected with said electrode parts, wherein said base materialis shaped into a form having an upper part and a bottom part wider than the upper part, so called a spread-toward-the bottom-shape, and wherein said each of the electrode partsare placed at positions near the bottom of said base materialwith the predetermined distance between every electrode parts in the width direction of the base material
