Abstract
A portable electronic device includes a circuit board and an antenna coil installed on the circuit board. The antenna coil includes a magnetic core and a coil wound at either side of an unwound portion. The winding direction of the coil is changed at either side of the unwound portion. When the length of the magnetic core is defined as X and the distance between two intersecting points at which a virtual line formed by projecting the central line of the magnetic core onto the circuit board intersects the outer periphery of the circuit board is defined as Y, the antenna coil satisfies Y≧X≧0.8Y.
