An object of the present invention is to provide an injection blow container that is excellent in moldability and impact resistance and furthermore, excellent in solvent resistance. The injection blow-molded container of the present invention comprises 60 to 95 parts by mass of a polyamide resin (A) and 5 to 40 parts by mass of a polyamide resin (B) (per 100 parts by mass in total of the polyamide resin (A) and the polyamide resin (B)), wherein the polyamide resin (A) comprises a diamine-derived constitutional unit and a dicarboxylic acid-derived constitutional unit, wherein 70 mol% or more of the diamine-derived constitutional unit is a constitutional unit derived from xylylenediamine, 70 mol% or more of the dicarboxylic acid-derived constitutional unit is a constitutional unit derived from α,ω-linear aliphatic dicarboxylic acid having 4 to 12 carbon atoms, and 30 mol% or less thereof is a constitutional unit derived from isophthalic acid; and the polyamide resin (B) comprises no constitutional unit derived from xylylenediamine, and is a polyamide resin having an alkylene group having 5 to 12 carbon atoms.
