PROBLEM TO BE SOLVED: To provide a connection method of a pipe arrangement for high-purity liquid, which enables easy and certain connection working, and reduces the generation of a particle from a connected connection after the working. SOLUTION: An edge of one side pipe inside and pipe outside of a synthetic resin pipe is chamfered. After the synthetic resin pipe is wiped with volatile solvent to dissolve or swell at the chamfered part and its vicinity, the end is inserted into a synthetic resin-made sleeve.
