PROBLEM TO BE SOLVED: To provide an endoscope device capable of changing over the color of emission light.SOLUTION: A light source device 10 includes a first semiconductor laser 22A, a second semiconductor laser 22B, and a phosphor unit 62. The first semiconductor laser 22A emits blue light having a wavelength of 460 nm, and the second semiconductor laser 22B emits bluish-purple light having a wavelength of 415 nm. The phosphor unit 62 absorbs the blue light emitted by the first semiconductor laser 22A to emit light having a wavelength of about 530 nm, and almost transmits the bluish-purple light emitted by the second semiconductor laser 22B. |
