PROBLEM TO BE SOLVED: To provide a nurse call apparatus which improves the visibility of a representative indicating lamp from a long distance since it is impossible to enlarge the size of the representative indicating lamp because of a restriction in the magnitude of a passage lamp. SOLUTION: The passage lamp is equipped with the representative indicating lamp which turns on and off a green light-emitting diode if the call of a general call button is detected, the representative indicating lamp which turns on and off a red light-emitting diode if the call of an emergency call button is detected, and the indicating lamp which turns on and off a blue light-emitting diode if the call of a toilet call button is detected. When the indicating lamp is set to one because of the restriction in the magnitude of the passage lamp, two or more green, red, and blue light-emitting diodes are equally arranged within the indicating lamp and a means which turns on and off a green, red, or blue light-emitting diode to a general, emergency, or toilet call respectively, is provided.
