ABSTRACT:
A fluid filter is provided with a case body defining therein a holder and having pressing portions formed on the internal wall surface of the case body. The pressing portions can compress a filter medium housed in the holder. The pressing portions are pressed against the filter medium housed in the holder to compress it and form a compressed region at a desired position of the filter medium, where the rate of capturing extraneous substances is increased. Thus, even if various sizes of the extraneous substances are contained in a fluid introduced through the inlet into the holder, the filter medium can capture the extraneous substances in its entirety. The degree of compression of the compressed region in the filter medium changes depending on the height of each pressing portion.
