Abstract: The optical-path configuration is made more compact and light is generated at high efficiency. Provided is a light-source apparatus including a light source that outputs monochromatic light; a wavelength conversion device that is disposed on an output optical axis of the light source and that generates light having a different color from that of the monochromatic light upon being irradiated with the monochromatic light; and a dichroic mirror that is disposed between the light source and the wavelength conversion device, that transmits the monochromatic light, and that, of the light generated at the wavelength conversion device, reflects back toward the wavelength conversion device light that has been scattered toward the light source so as to be parallel to the output optical axis.

Abstract: An endoscope illumination device includes: an illumination optical system including an entrance surface disposed along a circumferential direction centered on a predetermined axis and provided at one-end side in the direction of the predetermined axis, an emission surface positioned at an outermost side in a radial direction with respect to the predetermined axis and radially emitting illumination light entering from the entrance surface, a diffusion surface disposed at an intermediate position of an optical path of the illumination light between the entrance surface and the emission surface and transmitting and diffusing the illumination light; and a light emitting portion disposed closer to the one-end side than the entrance surface is and emitting, toward the entrance surface, the illumination light substantially in the direction of the axis.
