Abstract: An antenna device includes a power supply coil including wire patterns provided on or in magnetic layers and antenna coils including wire patterns provided on or in the magnetic layers. The power supply coil and the antenna coils include coil winding axes thereof coinciding with a lamination direction of the magnetic layers and generate magnetic field coupling to each other. The power supply coil is located on an inner side portion relative to the antenna coils when seen in the lamination direction. At least portions of the antenna coils are located on outer side portions relative to the power supply coil in the lamination direction. With this, an antenna device and a communication apparatus capable of communicating with a communication party reliably without forming an unnecessary communication path with a party-side coil are provided.

Abstract: A signal transmission cable as a signal transmission component includes a laminate including a first thin portion on one of the opposite ends in a first direction and a second thin portion on the other end in the first direction. A portion between the first thin portion and the second thin portion in the laminate is a main line portion. The thickness of the first and second thin portions is thinner than the thickness of the main line portion. The surface on one end in the thickness direction of the laminate defined by the main line portion and the first and second thin portions is a continuous flat surface. A connector for external connection is arranged on the surfaces of the first and second thin portions, on the sides in which each of the thin portions and the main line portion have a difference in level.

Abstract: An antenna device includes a resin multilayer board in which a plurality of resin sheets are stacked, and a coil conductor provided in the resin multilayer board. A plurality of line portions of the coil conductor are provided on a lower surface of the resin sheet. When a magnetic material core is preliminarily pressure-bonded to the resin sheet, the magnetic material core is fractured along the line portions and cracks occur. Thus, the resin sheet with the magnetic material core in which the cracks have been formed is fully pressure-bonded together with the other resin sheets.

Abstract: Provided is an LC composite component having a multi-layer substrate, a pattern coil, and a chip capacitive element. The multi-layer substrate is configured such that insulating layers are stacked. The pattern coil forms a coiled shape of which the coil axis extends along a stacking direction of the multi-layer substrate, and includes a coil conductor disposed between the insulating layers. The chip capacitive element includes a ceramic body having a relative permittivity higher than that of the insulating layers and counter electrodes. The chip capacitive element is at least partially disposed within the pattern coil.
