PROBLEM TO BE SOLVED: To selectively energize a coil such as a feeding coil at an arbitrary place when a plurality of coils such as a feeding coil are arranged over a wide area, and to make all feeding coils. It is not necessary to wire each of the coils as many as the number of coils to the power supply. SOLUTION: In a coil unit that can be selectively energized, a first reciprocating line extending in a first direction and a second reciprocating line extending in a second direction and intersecting the first reciprocating line. , Select the connection state or disconnection state of the coil connected to the intersection of the first reciprocating line and the second reciprocating line, the power supply connected to the second reciprocating line, and the second reciprocating line. It has one switch and a second switch that selects the connection state or disconnection state of the first reciprocating line. [Selection diagram] Fig. 1
