The present invention provides a copper-clad laminate that has a high reflectance with respect to visible light and ultraviolet light and exhibits superior resistance to ultraviolet light and to heat. The copper-clad laminate according to the present invention has a copper layer, a while-color layer, an adhesive layer, and a high-temperature conductive substrate having a thermal conductivity of 200 W/m·K or higher, in that order, wherein: the white-color layer is configured to have a composition in which a matrix of a highly ultraviolet-resistant organopolysiloxane includes therein a filler selected from any of BN, ZrO2, SiO2, CaF2, and diamond that exhibit a high ultraviolet reflectance; and the white-color layer and the high-temperature conductive substrate are bonded together using a thermosetting resin.
