A filter element comprising:
- 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 extending so as to be parallel to the second frame member formed along a longitudinal direction of the filter member,
- wherein the holder frame is composed of a pair of first frame members and a pair of second frame members, and at least one pair of reinforcing members are formed in a manner that one ends of the respective reinforcing members are connected to the first frame members, and
- wherein the reinforcing member is discontinuous with the second frame members.
