To prevent malfunction of a game machine due to electromagnetic wave noise by a wire harness to which a measure against noise is taken.

The wire harness 600 includes: a plurality of lines of electric wiring 601 for electrically connecting a plurality of electric components provided inside a Pachinko game machine; and a coil part 602 which forms a conductive wire electrically connected to the plurality of electric components in a coil shape and extends in almost the same direction as the extending direction of the plurality of lines of electric wiring. Since the plurality of lines of electric wiring 601 is disposed inside the coil part 602, when a current signal is caused to flow to the wire harness 600, a current flows to the conductive wire of the coil part 602, and a magnetic field rotating in the extending direction of the coil part 602 is generated so as to cover the coil-shaped conductive wire.
