Abstract
A filtration filter device that enables the sealability of a fluid channel to be improved is provided. A filtration filter device according to the present invention includes a first channel-forming member that has a first channel through which a fluid flows inside thereof, a second channel-forming member that has a second channel through which a fluid flows inside thereof, and a filtration filter that extends across the first channel or the second channel and that filters an object to be filtered that the fluid contains. The first channel-forming member includes an external thread. The second channel-forming member includes an internal thread. The first channel-forming member and the second channel-forming member have respective inclined surfaces that incline with respect to a screw direction in which the external thread is screwed into the internal thread at positions nearer than the external thread and the internal thread to the first channel or the second channel, and the inclined surfaces are in contact with each other with the external thread screwed in the internal thread such that the first channel and the second channel are in communication with each other.
