Abstract: A forced extraction molded article that can prevent damage during forced extraction is provided. The force extraction molded article (1) is formed of a polyarylene sulfide resin composition so as to include a cylindrical portion, wherein the cylindrical portion (10) has at a forward end portion a bulge (11), and an inner surface including a step in the outer diameter direction at the forward end portion, a portion excluding the step has a gradient such that the inner diameter of the cylindrical portion increases toward the forward end portion, and equation (a) below using a thickness D2 between a connection portion at the step on the inner surface of the cylindrical portion and the outer surface excluding the bulge, a height D4 of the step, and a height Dt of the gradient excluding the step on the inner surface of the cylindrical portion is satisfied. [ Equation ? 1 ] ? 0 . 0 ? 0 ? 1 ? D ? 2 2 - D ? 4 D ? 2 × D ? t D ? 2 ? 0 .

Abstract: The present invention relates to a polyarylene sulfide resin composition, which comprises polyarylene sulfide (A) and polyamide (B) as essential components, and further includes an organic phosphorus compound (C), which is selected from the group consisting of an aromatic phosphite compound and an aromatic phosphonate compound, and an inorganic phosphorus compound (D), which is selected from the group consisting from a metal salt of phosphorous acid and a metal salt of hypophosphoric acid as essential components, in addition to the polyarylene sulfide (A) and the polyamide (B); a manufacturing method thereof; and a surface mount electronic component. The polyarylene sulfide resin composition has excellent heat resistance, does not decrease mechanical properties such as bending strength even if heating treatment is performed under the high temperature condition by passing through a reflow furnace, and has excellent flame retardance.
