Abstract: The purpose of the present invention is to provide a copper pipe that is capable of exhibiting higher corrosion resistance with respect to formicary corrosion, can be suitably used in air conditioners and freezing equipment, and has excellent long-term anti-corrosion properties, and to advantageously improve the service life of equipment configured using such copper pipe. The copper pipe is configured from a material, which contains P (phosphorus) in a proportion of 0.15-0.50 weight %, in which oxygen content is 30 ppm by weight or less, and the balance is made of Cu and unavoidable impurities.
