CARD KEY WITH A FUNCTION FOR PERFORMING RADIO COMMUNICATION AMONG VEHICLE MOUNTED DEVICES

摘要

PURPOSE: A card key is provided to control the rising of manufacturing costs of a key main body by simplifying a process when a circuit board is set in a mold. CONSTITUTION: A key main body(10) is composed of a main body concave part(12), a battery holding concave part(13), a key holding concave part(14), a hook holding concave part(15) and a sheet body(20). The main body concave part is concavely formed in the predetermined depth of a main surface(S1). An electronic component is mounted in the major surface. The battery holding concave part is concavely formed from the main body concave part and is opened to the bottom surface of the main body concave part. The sheet body is inserted into the main body concave part. A battery holder, a key holder, and a hook holder are formed among the sheet body, the battery holding concave part, the key holding concave part, and the hook holding concave part.
