PROBLEM TO BE SOLVED: To provide a propylene-based polymer composition capable of giving a blow-molded product having excellent balance between rididity and impact resistance, having excellent transparency, surface smoothness (gloss), and surface hardness, having a good appearance in a weld part, and having excellent strength in a drop test. SOLUTION: This propylene-based polymer composition comprises [A] a specific propylene-based polymer and [B] an ethylene-α-olefin copolymer composition composed of [B1] an ethylene-α-olefin copolymer and [B2] an ethylene-based copolymer, wherein the ethylene-α-olefin copolymer [B1] has characteristics, such as an ethylene content of 55-80 mol% and a 4-20Cα-olefin content of 20-45 mol%, and the ethylene-based copolymer [B2] has other characteristics, such as another ethylene content of 85-99 mol% and a content of structural units (b) derived from a 3-20Cα-olefin or a cyclic olefin-based compound of 1-15 mol%.
