PROBLEM TO BE SOLVED: To provide a downsized inverted-F antenna. SOLUTION: The inverted-F antenna consists of a group conductor plate 10, a conductor plate 20, a feeding pin 30, a feeding plate 40, and a short-circuit plate 50. The feeding plate 40 is configured with an L-shaped plate section 42 in addition to a rectangular extension section 41. Hence the current path of the feeding plate 40 can be made longer than that of a conventional inverted- F antenna, and the reduction of the length of the current path due to the downsizing of the inverted-F antenna is cancelled, thereby realizing the miniaturization of the inverted-F antenna.
