A wavelength conversion member complex includes a wavelength conversion member, a joining material, and a heat dissipation member. The wavelength conversion member includes a support and a phosphor member. The support defines a through-hole extending from an upper surface to a lower surface. The support has a concave portion on the lower surface around the through-hole. The concave portion is spaced apart from the through-hole. The phosphor member is disposed in the through-hole and includes a phosphor. The lower surface of the phosphor member is continuous with the lower surface of the support. The joining material is disposed in the concave portion, and has a lower surface that is flush with the lower surface of the support. The heat dissipation member is disposed under the joining material and the phosphor member, and has an upper surface in contact with the lower surface of the joining material.
