<p>A thermal detector includes a substrate, a thermal detection element and a support member. The substrate has a concave portion, a bottom surface of the concave portion forming a light-reflecting curved surface. The thermal detection element includes a light-absorbing film. The support member supports the thermal detection element with a cavity being provided between the substrate and the support member. The light-reflecting curved surface and the light-absorbing film overlap each other in plan view, the light-reflecting curved surface having a projected area in plan view larger than an area of the light-absorbing film.</p> |
