1. A wavelength-conversion module comprising:
a base;
a wavelength-conversion member provided on the base; and
a joining member that joins the base and the wavelength-conversion member, wherein the joining member includes:
a sintered metal body having a porous structure containing voids;
a resin including a first resin portion that covers an outer surface of the sintered metal body and a second resin portion that is disposed in the voids; and
particles dispersed in the resin,
wherein a concentration of the particles dispersed in the first resin portion is greater than a concentration of the particles dispersed in the second resin portion.
