Provided are a living body stimulating electrode, a living body stimulating electrode apparatus, and a method for producing a living body stimulating electrode. The living body stimulating electrode has a flexible circuit board (FPC) between a living body stimulating electrode and a resin part. The resin part and the FPC are fixed with the living body stimulating electrode. Specifically, the flexible circuit board is disposed between the living body stimulating electrode and the resin part, and one or both of a stimulating electrode and a contact electrode constituting the living body stimulating electrode have an engaging part having a pressing part and a fixing part. The pressing part presses the flexible circuit board onto the resin part. Simultaneously, the fixing part is penetrated through a through hole formed in the flexible circuit board and pressed into a hole formed in the resin part, thereby fixed to and held by the resin part. The engaging part may be subjected to a chamfering process (the edge may be chamfered into an angulated plane or a round plane) to form an inclined plane or a curved (round) plane.
