PROBLEM TO BE SOLVED: To provide a resin composition for bottomed tube for vacuum blood- collecting tube, and a bottomed tube for vacuum blood-collecting tube, with excellent gas-barrier property, molding workability, and drop impact resistance. SOLUTION: The resin composition for a bottomed tube for vacuum blood- collecting tube is formed by combining 2-10 pts.wt. of poly(ethylene naphthalate) based copolymer (B) of which, ethylene-2,6-naphthalate unit is 80-95 mol%, and intrinsic viscosity (IV) is 0.40-0.65 dl/g, to 100 pts.wt. of poly(ethylene terephthalate) based copolymer (A) of which, ethylene isophthalate unit is 5-15 mol%, and intrinsic viscosity is 0.5-0.75 dl/g.
