To provide a light guide structure of a light emitting diode (LED) improving visibility of light emitted from the LED with an inexpensive simple structure.

The light guide structure of the LED for the claim 1 is configured that a small hole for display is formed on a surface plate of a device corresponding to the LED mounted in the device and an inside surface of the small hole for display is formed in a tapered shape spreading toward inside. The light guide structure of the LED for the claim 2 is configured such that a small hole for display is formed on a surface plate of the device corresponding to the LED mounted in the device where a peripheral edge of the small hole for display protrudes toward outside and an inner periphery of the small hole is formed in a tapered shape spreading toward inside.
