LIVING BODY-STIMULATING ELECTRODE, LIVING BODY-STIMULATING ELECTRODE DEVICE, AND PRODUCTION METHOD OF LIVING BODY-STIMULATING ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a lightweight living body-stimulating electrode having high connection accuracy.SOLUTION: A living body-stimulating electrode includes a flexible wiring board (FPC) between living body-stimulating electrodes and a resin part. Furthermore, fixing between the resin part and the FPC utilizes the living body-stimulating electrodes. In detail, the flexible wiring board is disposed between the living body-stimulating electrodes and the resin part, and each or one of a stimulation electrode and a contact electrode constituting each living body-stimulating electrode is formed with a locking part having a press-stopping part and a held part. The press-stopping part presses the flexible wiring board to a resin part direction and presses it. Simultaneously with it, the held part penetrates a through hole formed in the flexible wiring board, is pressed into a hole formed in the resin part, and is fixed and held to the resin part. Furthermore, the locking part is applied with chamfering machining (machining into a shape such as a corner face or a circular face by scraping a corner part) to form an inclined surface shape or curved surface shape (an R shape).
