Abstract
The present invention improves a method of bonding by welding a plurality of filter units each having a frame body made of a resin member so as to provide a filter unit panel having excellent pressure resistance. This filter unit panel is obtained by disposing a plurality of filter units so that the outer peripheral surfaces of adjacent filter units () and () are partially in contact with each other but at least a part of the upper surfaces () and/or the lower surfaces () of the adjacent filter units are spaced apart from each other, and then melting a bonding resin so as to cause the melted bonding resin to flow into a gap () between the spaced upper surfaces and/or a gap () between the spaced lower surfaces and to cure. The bonding resin is supplied from, for example, protruding portions () and () of the frame body. This welding method increases the bonding strength between the filter units and increases the pressure resistance thereof accordingly.
