おそれがある。However, in the conventional filter, since the filter medium portion and the frame are formed as separate parts, the number of parts and the number of assembling steps increase. In addition, since the frame is a resin molded product, a mold is required, which increases the cost. However, when the frame is abolished and the filter is composed of only the filter material, the rigidity of the filter may be insufficient, and the predetermined shape may not be maintained in the air conditioner. is there.
