Abstract
An electronic-component-integrated key has a head and a key plate. The head has an inside case portion, an outer sheath portion to be fixed to the inside case portion from outside, and a recessed portion that is formed in the inside case portion and arranged on the side of serrations of a key plate, not on the side of a head portion 1a of the key plate, so as to be substantially in parallel with the key plate. An electronic component is held within the recessed portion by a holder, and an abutment portion of the inside case portion is partially exposed to the outer surface of an opening formed in the outer sheath portion. During the process of manufacturing the electronic-component-integrated key, the following steps are taken when the key plate is arranged within a cavity of a mold. The key plate is fixed within the cavity by causing the abutment portion of the inside case portion to be abutted against the mold, and the outer sheath portion is thereafter formed on the outside of the inside case portion by charging molten resin into the cavity.
