Abstract: A body includes a support strut extending in a second direction. A first terminal includes a first fastening portion to exert a force on the support strut in a third direction perpendicular or substantially perpendicular to the second direction, a second fastening portion to exert a force on the support strut in a fourth direction opposite to the third direction, a first coupling portion coupled to the first protrusion and the second protrusion, and a contact portion coupled to at least one of the first fastening portion, the second fastening portion, or the first coupling portion, the contact portion extending in a fifth direction perpendicular or substantially perpendicular to the second direction.

Abstract: An antenna device includes an antenna body and a case that accommodates the antenna body. The antenna body includes a bobbin including a pair of side walls that extend in a first direction with inner surfaces that face each other in a second direction crossing the first direction. A winding is wound around the bobbin to surround the side walls while the axial direction is parallel to the first direction. A core is held by the side walls between the inner surfaces of the pair of side walls in an inner space defined by the winding. At least one of the inner surfaces includes inclined surfaces that overlaps the core in a third direction crossing both the first and second directions so as to be positioned closer to the core.

Abstract: A coil antenna having a capacitor that is not separated from a metal terminal or an electrode of a mounting substrate even when a root portion of a bobbin around which a coil is wound is bent by an external force. The coil antenna includes a bobbin; a coil wound around the bobbin; a capacitor connected to the coil; a base made of an insulating material formed integrally with the bobbin; and a mounting substrate having a plate shape with a pair of electrodes formed on a surface of the mounting substrate extended from the base for mounting the capacitor, such that the mounting substrate is held in a cantilevered manner in a winding direction of the coil.
