To provide a solar heat collection wall device capable of increasing the amount of air intake and reducing the cost.

The solar heat collection wall device is arranged and fixed in such a way that the spandrel panel 11 is spaced from the outer wall surface 2 of a building by a predetermined distance, and is configured to freely take air, which is in a space 12 between the outer wall surface 2 and the spandrel panel 11, into the inside of the building. In the solar heat collection wall device, crosspieces are provided in the peripheral part of the spandrel panel 11, and by the fixation of the crosspiece 24 of a side to the outer wall surface 2 with a space, there is formed an air inlet 15 which communicates with the space 12 over nearly the entire length of a side of the spandrel panel 11.
