Abstract:
1. An antennal holder holding an antenna that includes signal wiring and ground wiring being disposed on a single circuit board as either one of an external element and an internal element, respectively, each having one end electrically coupled with a circuit on the single circuit board for serving as the external element in a spiral shape, and the internal element in a spiral shape extending inside of the external element and in an axial direction of the external element at a predetermined distance, the external element and the internal element both extending in said spiral shapes to the respective end thereof electrically coupled with the circuit, the antenna holder comprising: a spacer for maintaining the predetermined distance between the external element and the internal element; an external tilt suppressor for suppressing a tilt of the external element from a direction orthogonal to the circuit board; a base having a base surface that is in parallel with a surface of the circuit board; an external fitting portion in the spacer for fitting to a part of a spiral of the external element at the predetermined distance on the base surface; and an internal fitting portion in the spacer for fitting to the internal element, wherein the external tilt suppressor protrudes from the base surface that has the spacer disposed thereon, and the external tilt suppressor has a contact with a predetermined portion of one of an internal periphery and an external periphery of the external element in the direction being orthogonal to the circuit board.
