摘要: A small antenna device having good communications performance and a wide communications area even when a metal plate is present in the antenna communications direction, even when the antenna is arranged, for example, inside a box-shaped metal case, and even when a through hole is used that has a smaller area than the antenna. This device comprises: the antenna; a rear surface cover overlapping with the antenna and being a conductor that faces the winding of the antenna; two first insulating areas provided in the rear surface cover and extending in a direction that intersects the winding axis of the antenna; and a second insulating area that connects between the first insulating areas. At least part of the area sandwiched by the first insulating areas faces the antenna.

摘要: A coil unit, a wireless power feeding device, a wireless power receiving device, and a wireless power transmission device are provided that can reduce high induced voltage on the metal part. A coil unit includes a power transmission coil, reactance circuits and that each form a resonant circuit together with the power transmission coil, and a metal part disposed on the same side as the back side of the power transmission coil. A ratio between a first reactance value of the first reactance circuit and a second reactance value of the second reactance circuit is set based on the ratio of the mean distance between the winding and the metal part in a part of the winding from the other end to the central portion to the mean distance between the winding and the metal part in a part of the winding from one end to the central portion.

摘要: In electronic devices, as a result of miniaturization, the distance between a mounting board and an upper board or a shield case and the like, or the distance between the mounting board and other electronic components mounted adjacent thereto has become smaller. An electronic component is provided with: an element body internally containing a circuit element; and a terminal formed on the element body. The terminal is formed over an end surface of the element body and a surface adjacent to the end surface. An insulating film covering the terminal is formed on the element body. The terminal is exposed from the insulating film at least at a mounting surface of the element body, and a plating film containing tin is formed on a portion of the terminal exposed from the insulating film.
