PROBLEM TO BE SOLVED: To solve the problem that, in the conventional antenna wherein a coil part is constituted of two stages for shortening a full length, an antenna case for housing the antenna requires an approximately half length of the full length of the antenna even in a contracted state, so that when mounting the antenna in a small-sized device, downsizing of the device is necessarily disturbed for securing the space for housing the antenna. SOLUTION: The present invention relates to techniques for an antenna including a folding part for freely folding an antenna body in the intermediate portion of the antenna body, wherein a tip end side antenna body portion from a position folded at the folding part can be housed in a groove-like housing part provided to the side face of an electronic device case.
