PURPOSE: A connection structure of synthetic resin pipe for use in underground burial and a connection method are provided to achieve a significantly enhanced water tightness while integrally bonding a thermally contracted connection pipe to the synthetic resin pipes. CONSTITUTION: A connection structure is characterized in that a thermally contacted connection pipe(2) having a diameter considering an outer diameter of a synthetic resin pipe(1) wraps around the outer surface of the connection portion between synthetic resin pipes(1) which are opposed to each other for pipe connection, the connection pipe(2) having at a rolled inner surface thereof an adhesive sealing material(3), thus the connection pipe(2) is tightly bonded to the connected outer surfaces of the synthetic resin pipes(1) by the adhesive sealing material(3) which is made up of an adhesive resin layer(31) deposited into a predetermined thickness onto the inner surface of the connection pipe(2).
