PROBLEM TO BE SOLVED: To provide a wiring piping material protective cover that can prevent the degradation of weather resistance and flame retardance, while suppressing production cost by suppressing usage of an ASA resin or an AES resin in a predetermined thickness.SOLUTION: A protective cover 10 is formed by coating inner layers 25, 34 made of a flame retardant ABS resin with outer layers 26, 35 made of an ASA resin. Also, in the inner layer 25 of a base mount 20, the outer layer 26 is formed on the outside excluding a first curved part 23 and an externally fitted part 24 (except, a first facing surface 24a). Alternatively, in the inner layer 34 of a lid body 30, the outer layer 35 is formed on the outside of the whole portion constituting a lid part 31, the whole portion constituting a second curved part 32, and a second facing surface 33a. Thereby, in an external fitting state of the lid body 30 to the base mount 20, all exposed on the surface is covered by the outer layers 26, 35. |
