PROBLEM TO BE SOLVED: To provide a key holder designed to easily find a desired key out of a large number of keys when the large number of keys are mounted to the key holder. SOLUTION: A plurality of keys 5 mounted to the key holder 1 are provided with light emitting diodes 7 with different luminescent colors from one another, and these light emitting diodes 7 are simultaneously lighted by a common switch 13. If a user of the key holder remembers the luminescent color of the light emitting diode provided at the desired key, the desired key can be found out very easily by the luminescent color not only in the daytime but also at night or in the dark.
