Classification: CPC A  G  H | IPC A  F  G  H

Claim 0:
1. A light source apparatus for endoscope comprising:
a light source configured to emit light;
a collective lens which focuses the light emitted from the light source;
a light shielding member which shields at least a part of the light emitted from the light source, and allows light, which is not shielded, to be transmitted as transmitted light;
an optical fiber on which, the transmitted light transmitted through the light shielding member is incident;
a holding member which includes a heat insulating member, and holds at least one of the light source, the collective lens, and the light shielding member, by fixing at a respective position thereof; and
a heat exhausting member which exhausts heat generated in the light shielding member to an outside of the holding member, wherein
a thermal resistance value in a thermal path of the light shielding member is smaller than a thermal resistance value of the heat insulating member,
a thermal resistance value in a thermal path of a connecting portion of the light shielding member and the heat exhausting member is smaller than the thermal resistance value of the heat insulating member, and
a thermal resistance value in a thermal path of the heat exhausting member is smaller than the thermal resistance value of the heat insulating member.
