摘要： An antenna includes antenna coil having a magnetic-material core and a coil conductor. The antenna coil is arranged toward a side of a planar conductor, such as a circuit board. Of the coil conductor, a first conductor part close to a first main face of the magnetic-material core and a second conductor part close to a second main face of the magnetic-material core are provided such that the first conductor part is not over the second conductor part in view from a line in a direction normal to the first main face or the second main face of the magnetic-material core. In addition, a coil axis of the coil conductor is orthogonal to the side of the planar conductor.

摘要： A spiral coil conductor defining its winding central section as a conductor opening section is formed on a flexible substrate. The flexible substrate has a U shaped bend along a line passing through the conductor opening section so as to envelop a magnetic material core. The magnetic material core is arranged in a state where its end face faces the bend of the flexible substrate, and the magnetic material core includes cut shapes provided at a portion of the end face. The portion at the end face faces coil conductor sections at the bend of the flexible substrate, and the cut shapes separate the portion apart from the coil conductor sections.
