A flexible pipe joint joins, in a bendable manner, a first pipe member provided with a partially spherical outer circumferential surface that protrudes outward in radial direction and a second pipe member provided with a partially spherical inner surface that can slide along the partially spherical outer circumferential surface. A sleeve made of a synthetic resin is inserted and fitted in a state of contact, bridging the inner circumferential surfaces of the two pipe members. The sleeve has a length that covers a cavity portion that opens inward in radial direction at a location where the two pipe members are joined together, and is elastically deformed substantially maintaining its circular tube shape when following a flexure of the two pipe members. The flexible pipe joint effectively suppresses impediments to the flow volume such as the deposition of sludge and grime while ensuring the intended bendability due to relative sliding of a partially spherical outer circumferential surface of a first pipe member and a partially spherical inner circumferential surface of a second pipe member.
