ABSTRACT:
A filter (15) for an inflator, comprising a cylindrical body (15a) formed by winding wires (16) therearound. The cylindrical body (15a) further comprises an inner peripheral part (21) and an outer peripheral part (22) covering the outer peripheral surface of the inner peripheral part (21). The inner peripheral part (21) is formed by radially stacking a plurality of first pattern layers (18a) thereon. The outer peripheral part (22) is formed by radially stacking one or more second pattern layers (18a) on the outer peripheral surface of the inner peripheral part (21). The first and second pattern layers (18a) and (18b) are formed of the wires (16) in net shapes. The mesh of the second pattern layers (18b) is smaller than that of the first pattern layer (18a).
