PROBLEM TO BE SOLVED: To provide a polyolefin resin composition having high mechanical strength and excellent durability in an environment in contact with high-temperature hot-water and steam. SOLUTION: The polyolefin resin composition contains (A) a modified polyolefin resin graft-modified with an unsaturated carboxylic acid and/or its derivative, (B) a filler, (C) a polyolefin resin and (D) at least one kind of phenolic antioxidant selected from a group of specific phenolic antioxidants. The amount of the component B is 5-80 pts. wt. based on 100 pts. wt. of the sum of the components A, B and C, the weight ratio of C/A is 99.9/0.1 to 60/40, the grafting amount of the unsaturated carboxylic acid and/or its derivative in the component A is≥0.3 wt.%, the melt flow rate of the component A is≤200 g/10 min, and the amount of the component D is 0.05-5 pts. wt. based on 100 pts. wt. of the sum of the components A, B and C.
