PROBLEM TO BE SOLVED: To provide an antenna holder which can improve retainability of antenna performance and its mounting operability for the antenna of a composition in which internal elements are arranged with spacing in an interior of an external element prolonged in a helical shape. SOLUTION: The antenna 100 arranges the internal element 120 inside of the external element 110 prolonged in the helical shape at a predetermined space, one of two elements 110 and 120 is made a signal line, and another is made a GND line. The antenna is held by a space maintaining unit 210 which maintains a space D3 of facing regions of the two elements 110, 120 to a predetermined value, and an antenna holder 200 which includes an external tilt suppression unit 220 which suppresses a tilt (swing) of the external element 110 in an orthogonal direction to the surface of a circuit board 10, and mounted on the circuit board 10.
