Abstract: A casing member for an in-vehicle camera, obtained by injection molding a resin composition that comprises 100 to 300 parts by mass of a total of a fibrous inorganic filler and a non-fibrous inorganic filler to 100 parts by mass of a polyarylene sulfide resin and has a content of an elastomer of 10% by mass or less, and satisfying the following conditions (A) and (B). (A) When a molded product of a predetermined shape is injection molded using the resin composition under predetermined conditions, an absolute value of (shrinkage rate in a direction perpendicular to a flow direction)−(shrinkage rate in the flow direction) is 0.5% or less. (B) A water absorption rate of a molded product of a predetermined shape that is injection molded using the resin composition under predetermined conditions is 0.3% or less when subjected to a predetermined hot water immersion test.
