The present invention relates to an airbag housing cover formed from a thermoplastic elastomer composition containing a propylene-based random copolymer and a styrene-based elastomer having a glass transition temperature in the range of-65 DEG C to-45 DEG C (inclusive), the content of the styrene-based elastomer in 100% by mass of the thermoplastic elastomer composition being less than or equal to 1% by mass and less than or equal to 1% by mass. The total content of the propylene random copolymer and the styrene elastomer is more than 40% by mass but 100% by mass or less.
