Provided is a corona-resistant resin composition which has an excellent balance between corona resistance and mechanical properties. The present invention relates to a corona-resistant resin composition which contains at least a polyarylene sulfide resin, a silicone polymer and a non-conductive inorganic filler, and which is configured such that: the silicone polymer is composed of one or more polymers selected from the group consisting of acrylic silicone copolymers and the like; the non-conductive inorganic filler is composed of at least one of a fibrous inorganic filler, a granular inorganic filler and a plate-like inorganic filler, and in cases where a granular inorganic filler or a plate-like inorganic filler (excluding glass flakes) is contained, at least a fibrous inorganic filler is also contained; and the content of the non-conductive inorganic filler, the content of the silicone polymer and the total content of the silicone polymer and the non-conductive inorganic filler are within specific ranges, respectively.
