To lessen radial noises and make the whole of the size of an illuminator device small by applying plural illuminating elements of semiconductors that make illuminating light emitted, a direct current power source which controls and turn on each of the illuminating elements of semiconductors, a device for gathering radial lights from each of the illuminating elements of semiconductors around the starting point of the illumination.
Inside the main body 2 of the illuminator for endoscope, a illuminating unit 3 that is composed of plural white LEDs 4 which are circularly arranged on flat board-shaped substrate 5 for attaching LEDs. A white-colored single tip is used for each white LED 4, for example, a composition of a blue LED of InGaN and a fluorescent material. In the main body 2, connector 10 for light guide 9 to which the light guide 9 for endoscope is connected as it can be attached to or detached from. Inside the main body 2, lens 11 for gathering lights are arranged between the connector 10 for the light guide and the illuminating unit 3. A stable amount of light can be supplied to the light guide 9 by controlling and turning on white LED 4 by direct current power source 12.
