Abstract: A filtration filter device that includes a filtration filter that filters an object to be filtered that a fluid contains, and a holding member that holds an outer circumferential portion of the filtration filter. An annular projecting portion that projects in a thickness direction of the holding member and that defines a channel through which the fluid flows is formed on one main surface of the holding member. A recessed portion that is recessed in the thickness direction of the holding member and that has an inner diameter larger than an inner diameter of the projecting portion is formed on the other main surface of the holding member. The filtration filter is disposed inside the projecting portion of the holding member.
