Claim 25:
26. A light source module comprising:
a light source section; and
a wavelength conversion element that is excited by excitation light from the light source section to emit fluorescent light, wherein the wavelength conversion element includes:
a phosphor layer including a plurality of phosphor particles, the phosphor layer having a gap therein;
a refrigerant that cools the phosphor layer;
a refrigerant transport member provided in contact with the phosphor layer, the refrigerant transport member circulating the refrigerant, wherein the refrigerant is circulated by capillary force generated in the phosphor layer and the refrigerant transport member, and wherein a capillary force in the phosphor layer is greater than a capillary force in the refrigerant transport member; and
a housing in which the phosphor layer, the refrigerant, and the refrigerant transport member are encapsulated.
