There is disclosed a detecting device including a detecting portion that detects contact of a person with a contacted body, the detecting portion including: an insulating body, the insulating body being sheet-shaped; an electrode, the electrode being sheet-shaped, being disposed at at least one side surface side of the insulating body, and being less extensible than the insulating body; and a positioning hole, the positioning hole being formed so as to penetrate through the insulating body and the electrode, and the insulating body and the electrode being positioned by the positioning hole.

Detecting device and steering wheel

A sensor electrode and an insulating body are coupled together by a hot melt member in a sensor of a steering wheel. The sensor electrode makes contact with the insulating body at first protrusions so as to form through holes in the hot melt member. The hot melt member is accordingly able to stretch easily due to the through holes, enabling a high extensibility for the sensor to be achieved.

Detection mechanism

A steering wheel including: a detecting portion wound on a base portion that has a concave groove portion, the detecting portion being configured to detect contact of a person; an electrode that is sheet-shaped, the electrode structuring the detecting portion; and a convex portion formed at a side of the concave groove portion of the electrode, the convex portion projecting-out in a width direction of the electrode.
