PROBLEM TO BE SOLVED: To provide a heat collection member capable of improving a photovoltaic heat collection efficiency.SOLUTION: A heat collection member 2 comprises: a thermal storage member 21, which is installed on a vent layer 3 formed between a multiple-staged solar battery panel 1 disposed on a roof 41 along a gradient direction X1 and the roof 41; and a heat insulation member 22, which partly covers the thermal storage member 21. The vent layer 3 communicates to an indoor space through an aperture 42 formed on the roof 41 at a position facing the uppermost stage of the solar battery panel 1 in the gradient direction X1 among multiple-staged solar battery panel 1. The thermal storage member 21 is installed at a position lower than the aperture 42 in the gradient direction X1 leaving a part of the vent layer 3. The heat insulation member 22 comprises: a first covering part 221, which covers a part facing the solar battery panel 1 on the thermal storage member 21; and a second covering part 222, which covers an upper side of the thermal storage member 21 in the gradient direction X1.SELECTED DRAWING: Figure 1 |
