PROBLEM TO BE SOLVED: To provide a waterproof layer protective material useful for protecting a waterproof layer; a waterproof material to be placed on the uppermost layer of the waterproof layer; a method of manufacturing the waterproof layer protective material and waterproof material; and a waterproofing construction method (construction method for waterproofing). SOLUTION: A composite metallic oxide pigment including an oxide of Bi and/or Y and an oxide of Mn has an excellent reflective performance against heat ray such as sunlight. Therefore, the composite metallic oxide pigment including the oxide of Bi and/or Y and the oxide of Mn is useful for the waterproof layer protective material, the asphalt exposure waterproof material, and the waterproofing construction method.
