Since the front part of the LED has a triangular shape, the emitted light of the infrared light LED 23 reaches the rear of the housing J, so that even if the electric device to be operated is located behind the remote controller A, Operation becomes possible. In addition, since the reflection / transmission material 24 is provided on the front surface of the housing J,
The light emitted from the infrared LED 23 is emitted not only in the front-rear direction and the front direction of the housing J but also in the back direction, so that the operation of the electric device can be performed regardless of the direction of the remote controller A.

That is, regardless of the position of the electric device to be operated and regardless of the direction of the remote controller A, the emitted light of the infrared LED 23 reaches the electric device, and therefore the user does not care about the position of the electric device.
