Abstract
A push-button switch includes a wiring board having a first surface on which electronic components are mounted. The push-button switch is used for an immobilizer system and supplies power to a portable device from the first surface side of the wiring board. The push-button switch includes a coil antenna and a conductor pattern. The coil antenna includes a magnetic core and a coil conductor wound around the magnetic core. The coil antenna is attached to a second surface of the wiring board. The conductor pattern is formed in at least one wiring layer so as to surround the coil conductor in plan view. The wiring board has an inner layer including the at least one wiring layer. A direction of current flowing through the coil conductor is the same as a direction of current flowing through the conductor pattern.
