Abstract
Disclosed is a transparent key which facilitates position control of a marking portion in the direction of thickness of a key. The transparent key has a transparent key body, a color layer which is formed at a bottom surface of the key body, and is visible through the key body at a time of non-illumination, a first area, and a transparent second area covering the first area from a top surface side. Laser marking is performed more easier for the first area than for the second area.
