Abstract: PURPOSE:To obtain the selective absorption film having a high total efficiency with a good reproducibility and inexpensive cost by a method wherein coating treatment liquid, containing magnesium hydroxide, chromic acid and polyester particle, is coated on the surface of an iron base plate, thereafter, it is heated to a temperature of 300- 500 deg.C. CONSTITUTION:Cold-rolled steel plate, having thickness of 0.3mm. and easily available normally, is employed as the base material of a heat collecting plate. The mild steel plate having flat and smooth surface is degreased by a non-etching type degreasing agent and is washed and dried, thereafter, the coating treatment liquid, obtained by adding 5-30wt% of polyester {[-OC.(C6H4).CO.O(CH2)2O-]n} into a solution con taining 5-30wt% of magnesium hydroxide and 10-40wt% of chromic acid, is coated on the surface of the mild steel plate by a roll, thereafter, it is dried.
