Abstract

A filter portion of a filter includes a plurality of bag-like members. The bag-like members are formed in a container shape having an opening and disposed with intervals therebetween. The periphery of the opening of each bag-like member is supported by a supporting member, and the bag-like members are mutually connected by the supporting member. Consequently, the strength of the filter portion comprising the bag-like members is improved.
