PROBLEM TO BE SOLVED: To provide an adhesion-joining structure for reducing a step on an outer surface of a joined part and keeping watertightness in a connection of a rise pipe at a lower part of a synthetic resin made catch basin to an upward connection part of an invert member. SOLUTION: In a synthetic resin connection structure, a lower end part of a riser pipe which is a component of a synthetic resin catch basin is fitted to an upward connection part of an invert member which is also a component thereof, and connected thereto via an adhesive. One of the lower end part of the riser pipe and one of the upward connection part of the invert member are spigots and the others are sockets. A butting wall having the outside diameter as that of the pipe on the socket side is provided to an end of the spigot, an end face of the pipe on the socket side is abutted on a side wall of the butting wall, an outer circumferential surface of the spigot forms a tapered surface expanded toward the end, and an adhesive is filled between an inner circumferential surface of a pipe end part on the spigot side and the tapered surface.
