Abstract

PURPOSE: The filter element which comprises a separating membrane tape in spiral form while butting the continuous one end in the width direction to the other end, winding another tape on this butt and bonding the same at a width narrower than both tape width and which is free from production of cracking of the separating membrane sheet.
CONSTITUTION: A separating membrane sheet 6 composed primarily of synthetic resins is wound in spiral form so as to butt one continuous end in the width direction to the other continuous one end. Another tape 7 is wound on this butt portion 9 and is bonded at the adhesion bonding part 8 (1W5mm wide) of the width narrower than the width of the tapes 6, 7. At this time, it is necessary to make the width to be thermally bonded as small (2W5mm) as possible. Since it is difficult to wind such a slender tape without crooking with a poreless tape 7, the tape 7 is made to a separating membrane tape of an arbitrary broad width and this is bonded at the narrowest possible width. A plurality of such filter elements 11 are put in a pipe 10 to constitute a module.
