PROBLEM TO BE SOLVED: To provide a filter unit panel with excellent pressure resistance by improving a method for bonding by welding a plurality of filter units having resin members as frames. SOLUTION: In a state where the plurality of filter units are arranged so that at least parts of upper faces 11 and/or lower parts 12 is separated, while parts of outer peripheral faces of the adjacent filter units 100a, 100b are in contact with each other, molten bonding resin is poured in a space 15 between the separated upper and/or lower faces and solidified. The bonding resin is fed from, for example, protruding parts 10a, 10b of the frame. In this bonding method, the bonding strength of the units is increased and the pressure resistance is improved.
