PROBLEM TO BE SOLVED: To provide a bar antenna which enables an inductance value to be properly finely adjusted and can be temporarily fixed. SOLUTION: In the bar antenna, a bobbin 3 which has a coil 2 wound around a core 1 made of a ferrite material and is made of an insulating resin is arranged, and detaining parts 4 biting into the surface of the core 1 are formed in an end part of the bobbin 3. The neighborhoods of the detaining parts 4 and the core 1 are made to adhere to each other with an adhesive 5. A plurality of detaining parts 4 are arranged like a circle at approximately regular intervals and have front ends protruded slightly inward in the peripheral direction. COPYRIGHT: (C)2004,JPO
