PROBLEM TO BE SOLVED: To provide a sheet material, excellent in resistance to oxidation-caused heat generation and acid gases, and capable of being formed under heating (e.g. work heating and shaping cold press molding). SOLUTION: This formed product of polypropylene fibers is composed of polypropylene fibers and glass fibers fusing with each other, wherein the polypropylene fiber is made of a polypropylene composition containing a sulfur-, phenol- and phosphorus-based antioxidant each at 0.01 to 1 pts.wt., and neutralizer at 0.01 to 0.5 pts.wt. per 100 pts.wt. of polypropylene.
