A resin molding including a polyolefin, a polyamide in a content of 1 part by mass to 50 parts by mass per 100 parts of the polyolefin, carbon fibers in a content of 1 part by mass to 50 parts by mass per 100 parts by mass of the polyolefin, organic fibers in a content of 1 part by mass to 20 parts by mass per 100 parts by mass of the polyolefin, and a carboxylic anhydride-modified polyolefin as a compatibilizer in a content of 1 part by mass to 10 parts by mass per 100 parts by mass of the polyolefin, where a proportion of a carbon fiber and an organic fiber each having a fiber length in a range of 1 mm to 20 mm to all the carbon fibers and the organic fibers is 1% to 20% by number.
