    摘要: Provided are a thermoplastic elastomer composition having excellent injection moldability, feel, scratch resistance, and flame retardancy and a molded article thereof. The thermoplastic elastomer composition contains components (A) to (D), listed below, wherein a content ratio of the component (D) is 0.01 to 30 parts by mass per 100 parts by mass of a total of the components (A) to (D). The molded article is formed by molding the thermoplastic elastomer composition. Component (A): a propylene-based polymer; component (B): a block copolymer and/or a hydrogenated product thereof, the block copolymer including at least two polymer blocks P and at least one polymer block Q, the at least two polymer blocks P primarily including aromatic vinyl compound units, the at least one polymer block Q primarily including conjugated diene compound units; component (C): a softening agent for a hydrocarbon-based rubber; and component (D): a halogen-containing flame retardant.
