Abstract
A filter element includes: a filter member formed of a non-woven fabric formed by laminating a plurality of non-woven fabric layers and folding the thus formed non-woven fabric in form of pleat having a predetermined size along a width direction of the filter member; a holder frame formed of a soft material and disposed along an outer peripheral edge of the filter member, the holder frame being constituted by first and second frame members; and a reinforcing member having one end connected to the first frame member disposed along the width direction of the holder frame and having another end formed as a free end free from connection. The reinforcing member extends so as to intersect the width direction of the filter member.
