PROBLEM TO BE SOLVED: To provide a plate membrane element having new structure capable of stably maintaining a connecting condition of an external tubular body to a nozzle part projecting upward from filter plate without increasing the size of welding equipment, drastically increasing the production cost, and complicating its structure.SOLUTION: There is used a filter plate 20 made of thermoplastic synthetic resin. The bottom end side of the nozzle part 40 arranged at the upper edge part of the filter plate 20, there is arranged an end side projection part 46 which projects outward at both surface of the filter plate 20 and forms inclination surfaces 48, 48 projecting largely outward in a gradual manner from downward to upward. |
