The invention discloses a foam pump valve membrane structure and a manufacturing method thereof, and aims to provide the foam pump valve membrane structure with good forming quality and good sealing effect and the manufacturing method thereof. The foam pump valve membrane structure comprises a valve membrane body, an outer elastic membrane and an inner elastic membrane are arranged on the outer side wall and the inner side wall of the valve membrane body respectively, the outer elastic membrane is annularly fixed to the outer side of the valve membrane body and fixedly connected with the valve membrane body, and the inner elastic membrane is annularly fixed to the inner side of the valve membrane body and fixedly connected with the valve membrane body. The foam pump valve membrane structure has the beneficial effects that installation is convenient, and time and labor are saved; the sealing effect is good; the forming quality of the valve membrane is improved; friction force between the valve membrane and a m
