The present invention is a catheter comprising a thermoplastic polyester elastomer resin composition containing a thermoplastic polyester elastomer (A) obtained by bonding 20-65 mass% (inclusive) of a hard segment and 35-80 mass% (inclusive) of a soft segment, and a polycarbodiimide compound (B), the thermoplastic polyester elastomer (A) being obtained by bonding 20-65 mass% (inclusive) of a hard segment and 35-80 mass% (inclusive) of a soft segment. The hard segment is composed of a polyester having an aromatic dicarboxylic acid and an aliphatic or cycloaliphatic diol as constituent components, and the soft segment contains an aliphatic polycarbonate, and the content of the aliphatic polycarbonate is less than or equal to 100 parts by mass per 100 parts by mass of the thermoplastic polyester elastomer A; the thermoplastic polyester elastomer resin composition contains 0.1 parts by mass or more and 5 parts by mass or less of the polycarbodiimide compound B. 本发明为一种导管，其包含含有热塑性聚酯弹性体A和聚碳化二亚胺化合物B的热塑性聚酯弹性体树脂组合物，所述热
