摘要

A wireless communication device (100) includes a first casing (10) and a second casing (20), and is switched between at least a first state and a second state by displacement of the first casing (10) and the second casing (20). The first casing (10) includes a first conductor (15) and a conductor element (36a) connected thereto. The second casing (20) includes a second conductor (25), and is connected to the first casing (10) so as to be rotationally displaceable with respect to each other around a perpendicular axis. In a first state, an opposite region (241) in the second conductor (25) and the conductor element (36a) are located at positions opposite to each other, and the conductor element (36a) and the second conductor (25) allow electrical conduction to each other at a predetermined frequency. In a second state, the electrical conduction state is different from that in the first state.
