Abstract
A weld joint has a weld portion for being welded and bonded to a rim portion around an opening of a resin fuel tank. The weld portion is made of a resin alloy material that is obtained by alloying EVOH or PA with a modified HDPE. A highly-weldable layer is provided in an extremity portion of the weld portion throughout an entire circumference of the weld portion. The highly-weldable layer is made of HDPE and/or a modified HDPE having good weldability to the resin fuel tank. An extremity end surface of the highly-weldable layer serves as a weld surface for welding the weld portion to the resin fuel tank.
