摘要

A pipe (10) includes a polyethylene-based resin layer (21) which comprises a polyethylene-based resin composition as a main component. The polyethylene-based resin layer (21) forms a pipeline-material inner surface (10a). The polyethylene-based resin composition has a calcium concentration of 10-60 ppm.
