PROBLEM TO BE SOLVED: To provide an antenna device for RFID which can be surface-mounted without an increase in the thickness of a housing of a portable electronic apparatus and has high receiving sensitivity. SOLUTION: The antenna device includes a magnetic core 2 that is surface-mounted on a circuit board 1. The antenna device further has a pair of coil sections A, B formed spaced apart from each other a prescribed distance (d), and the coil sections A, B are interconnected by a connection conductor 6. Ends of the magnetic core have a bend extending to the circuit board side on which the magnetic core is mounted. COPYRIGHT: (C)2008,JPO&INPIT
