To solve such a problem that generation of abrasion powder causes electric noise or poor insulation thus requiring maintenance and inspection every time when abrasion powder is generated, and to prevent poor insulation by not generating abrasion powder.

The slip ring device 1 comprises a shaft body 2 supported rotatably about a shaft, a plurality of electrode rings 7 laminated rotatably on the shaft body 2 through an air gap and having a gold pattern 17 formed round each inner peripheral wall, a plurality of electrode rings 8 having a gold pattern 12 formed round each outer peripheral wall, and a plurality of stages of gold wire brush 4 provided for each electrode ring 7, 8 and having a plurality of gold wires, respectively. The midway part of each gold wire of these gold wire brushes 4 touches the gold pattern 12, 17 to configure a gold contact slip ring.
