A1

Disclosed is an indicator instrument that can supply stable electrical power to a light source. The indicator instrument—which is provided with: a display member (10) that has a display unit (13a); a circuit board (20) disposed at the rear of the display member (10); a drive device (40) that is conductively mounted to the circuit board (20); an indicator member (50) that has a base (51) mounted to the rotating shaft (30) of the drive device (40) and positioned at the periphery of the rotating shaft (30), and an indicator unit (52) that indicates a display unit (13a); and a light source (57) disposed at the indicator member (50) in order to cause the indicator unit (52) to emit light—is provided with: a first coil-shaped wiring section (22) formed on the circuit board (20); a coil (91) that is provided towards the base (51) in a manner so that electromagnetic induction with the first coil-shaped wiring section (22) is possible; and a first flexible substrate (58) for electrically connecting the coil (91) and the light source (57); and the indicator instrument has a configuration wherein electricity is supplied to the light source (57) via the first flexible substrate (58) by means of the electromagnetic induction effect between the first coil-shaped wiring section (22) and the coil (91).
