To provide a heat-collection aluminum roof tile for a solar system house with a high heat exchange rate, which efficiently absorbs solar heat at its surface and efficiently releases the absorbed solar heat to heat-collection circulating air at the back.

The heat-collection aluminum roof tile consists of an aluminum roof tile main body 1, a plurality of protruding stripes 2 formed over the surface of the main body 1 and a plurality of vertical recesses 3 formed at the back. The protrusions 2 and recesses 3 are made in one with the main body 1. This enables the surface of a heat-collection aluminum roof tile to efficiently absorb solar heat, its back to efficiently convey heat to the recesses 3, and the recesses 3 to efficiently discharge heat to heat-collection circulating air.
