PROBLEM TO BE SOLVED: To provide a light-emitting pointer instrument capable of suppressing costs by reducing the number of parts, achieving a high-luminance light emitting pointer, providing satisfactory visibility, hardly causing contact failure or the breaking of wires, and improving durability. SOLUTION: The light-emitting pointer instrument is provided with an oscillation circuit 51 having a transmitting coil 3 as a means for transmitting an electromagnetic field in the vicinity of the pointer 21; a resonant circuit part 25 having a receiving coil 22 as a receiving means for generating a received current in the electromagnetic field inside the pointer 21; and an LED 24 as a light source for emitting light by the received current of the resonant circuit part 25. The pointer 21 emits light by the LED 24, and the pointer 21 itself emits light without electrical connections. COPYRIGHT: (C)2004,JPO
