PROBLEM TO BE SOLVED: To reduce useless consumption of a battery for supplying electric power to a radio circuit in a wireless device for a smart plate from the time of shipping of the device to a certain period, wherein the device requires its radio circuit and the battery to be accommodated air-tightly in a cabinet after the period. SOLUTION: The wireless device for the smart plate inactivates the battery when a switch operation unit is pushed so that a recess 93 or a recess 94 may come to the position of a switch 4, but it activates the battery when the unit is pushed so that these recessed come to other position.
