Abstract: This invention is a sunlight-to-heat converting member containing chromium silicide having an element ratio of Cr to Si from 1:1.6 to 1:4.7. This invention is also a sunlight-to-heat converting stack including a layer of the sunlight-to-heat converting member and a metal layer. This invention is also a sunlight-to-heat converting device including a light collecting part, either or both of a container and a flow path where sunlight is collected by the light collecting part, and a heating medium housed in either or both of the container and the flow path. The sunlight-to-heat converting member or the sunlight-to-heat converting stack is formed on a surface of either or both of the container and the flow path. The sunlight-to-heat converting member, the sunlight-to-heat converting stack, and the sunlight-to-heat converting device of this invention can convert light to heat efficiently.
