ANTENNA DEVICE AND ELECTRONIC APPARATUS

摘要

An invented antenna device includes a spiral coil having terminal wires extending from an inner periphery side thereof and from an outer periphery side thereof, a magnetic layer supporting the spiral coil and being formed with a cutoff portion extending from an inner periphery side thereof to an outer periphery side thereof, and a circuit board having a pair of terminal portions for connecting to the terminal wire and a connecting terminal for connecting an external circuit. The circuit board is placed in the cutoff portion, and the terminal wire extending from the inner periphery side of the spiral coil is coupled to the terminal portion located on an inner periphery side of the circuit board whereas the terminal wire extending from the outer periphery side of the spiral coil is coupled to the terminal portion located on an outer periphery side of the circuit board.
