A pipe joint (1) comprising: a tubular main body (10) having a flow path inside, which is formed of a resin comprising a copolymer having one or more selected from a vinyl cyanide monomer unit and an acrylic monomer unit, a rubber component, and an aromatic vinyl monomer unit; and a socket section (20a) integrally formed with the main body (10), wherein: the main body (10) has a foamed resin layer (30) and a non-foamed resin layer (50) covering the foamed resin layer (30); the amount of the rubber component in the foamed resin layer (30) as determined by pyrolysis-gas chromatography/mass spectrometry is within a specific range; the amount of the rubber component in the non-foamed resin layer (50) is within a specific range; and a ratio (La/La) of length (La) from a base end (21a) to an opening end (22a) of the socket section (20a) to a thickness (da) of the socket section (20a) at the opening end is 2.0 or more and 10.0 or less.
