PROBLEM TO BE SOLVED: To restrain electrostatic induction noise of a biological signal on the side of a bioelectrode, regardless of presence/no presence of a shield in a cable to be connected to the electrode part of the bioelectrode.SOLUTION: In an electrode cover 100, a base material 102 covers the electrode part 152C of the bioelectrode 150 to be mounted on the body surface of a living body. A conductive film 104 is arranged on the base material 102 by insulation from the electrode part 152C and electric charges are electrified by electrostatic induction with an electrified body adjacent to the electrode 152C. A conductive adhesion gel 108 electrically connects the conductive film 104 to the body surface, and the electrified electric charges of the conductive film 108 are discharged to the living body.
