Abstract
A method of connection of piping members made from a polyphenylene ether-based resin composition characterized in that the piping members made from a polyphenylene ether-based resin composition are comprised of a polyphenylene ether-based resin composition which has a polyphenylene ether-based resin in “a” parts by mass and a polystyrene-based resin in “b” parts by mass as essential ingredients, has the “a” and “b” satisfying the relationships of a+b=100 and a:b=(10 to 90):(90 to 10), and has a melt flow rate after kneading of 1.0 to 10.0 g/10 min, comprising heating and melting an outer circumferences of the pipe part and an inner circumferences of the mouth part of the piping members made from a polyphenylene ether-based resin composition parts by mass/100 parts by mass)}]±10° C. then inserting the pipe part into the mouth part to melt bond them.
