Abstract:
[Problem] To improve the strength and producibility of a filter having a filtration material in a pleated shape. [Solution] This filter (40) comprises a filtration material (41) having a partitioned surface (43) that is partitioned by mountain-fold pleats (42) and valley-fold pleats (42), and end plates (48, 49) that are fixed to the two end sections of the filtration material (41) and that maintain the filtration material (41) in a pleated shape. The filtration material (41) includes a plurality of filtration sections (45a, 45b, 45c), and intermediate sections (46a, 46b) provided between adjacent filtration sections. In the filtration sections, the angle formed by adjacent partitioned surfaces (43, 43) is greater than 0°. In the intermediate sections (46a, 46b), the angle formed by adjacent partitioned surfaces (43, 43) is 0°.
