PROBLEM TO BE SOLVED: To provide a heat transfer pipe with a simple structure, manufacturable in a simple production process at low cost, and having excellent corrosion resistance and excellent heat exchange efficiency between a fluid flowing in the outside, and a fluid flowing in the inside and having a high heat transfer characteristic. SOLUTION: This heat transfer pipe 7 comprises a small-diameter metal pipe 1, and a heat transfer body 5 of a corrosion-resistant metal disposed on the peripheral face of the small-diameter metal pipe 1. The heat transfer body can be a thin-thickness metal pipe installed on the peripheral face of the small-diameter metal pipe. COPYRIGHT: (C)2004,JPO
