PROBLEM TO BE SOLVED: To provide a pneumatic solar collector capable of producing warm air by utilizing sunlight, improving heat collecting efficiency, being miniaturized and easy in assembling work. SOLUTION: This pneumatic solar collector has a hollow heat collection case 2 of which the top face is coated with a transmission body 21 having high sunlight transmittance, and a sheet-shaped heat collecting material 3 disposed in a state of being inclined to block the heat medium air flowing in the heat collection case 2, and having fine pores through which the heat medium air passes, and lower voids 31 having ventilation widths to allow the heat medium air to rise along a back face of the sheet-shaped heat collecting material 3 are formed at a lower portion of the sheet-shaped heat collecting material 3.
