To provide a lightweight and inexpensive heat transfer pipe by forming a fin member of a resin material externally provided on the heat transfer pipe, and to provide a product with thermal conductivity equivalent to a heat transfer pipe externally provided with a metal fin member.

The heat transfer pipe 1 is formed by annularly and spirally adhering the resin fin member 3 to an outer circumference of a pipe body 2. The resin fin member 3 can also be spirally arranged on the pipe body 2 by adhering a long side one side end face of a band like flat plate member to an outer circumferential face of the pipe body 2.
