<P>PROBLEM TO BE SOLVED: To provide an illumination device for stably obtaining illumination light without a noise of speckle interference at any time and an endoscope using this. Ž<P>SOLUTION: In the illumination device which includes a light source 65 for emitting light of a first wavelength band and a fluorescent body 69 which excites and emits light of a second wavelength band by the light of the first wavelength band and obtains the illumination light by mixing the light of the first and second wavelength bands, the light source 65 is a laser diode of a broad area type, and a high-frequency wave superimposing means 59 for making the laser diode undergo multimode oscillations by superimposing a high-frequency signal on a driving current supplied to the laser diode is provided.
