An antenna coil, viewed in the direction of the stacking of insulation bodies, is configured at each turn with a first conductor pattern which forms a first side, a second conductor pattern which forms a second side, a third conductor pattern which forms a third side, and a fourth conductor pattern which forms a fourth side. The first conductor pattern is formed in a first layer. The second conductor pattern is formed in a second layer which is different from the first layer. The third and fourth conductor patterns are formed reaching from the first layer to the second layer. The first through fourth conductor patterns are positioned in each insulation layer such that the direction of lines which join the centers of gravity of winding shapes from the conductor patterns of a given turn is inclined with respect to the stacking direction of the insulation layers. |
