To provide a roof structure capable of firmly resisting a blow-up force acting on a solar cell module, even if the solar cell module is laid along an edge of eaves of a building.

This roof structure includes the solar cell module 10, the surface of which is fitted with a solar battery panel 12, and an edge-of-eaves blow-up prevention implement 110 which is fixed to the edge of the eaves of the top surface of the building. The roof structure is characterized in that an eave-side end of the solar cell module 10 arranged at the edge of the eaves is held by the edge-of-eaves blow-up prevention implement 110 when the solar cell module 10 is laid on the top surface of the building so as to constitute a roof R.
