Abstract
The present invention provides a filter retainer capable of suppressing the retention of a filtered fluid. The filter retainer is a filter retainer (10) that forms flow paths (11) by being sandwiched between two filter media, wherein the filter retainer (10) is an approximately circular-shaped plate having the flow paths (11) on both surfaces thereof, and in the radial direction of the filter retainer (10), the vertical cross-sectional area of each flow path (11) on the outer peripheral side is smaller than that on the center side. In the filter retainer (10) according to the present invention, each flow path (11) is narrower on the outer peripheral side than on the center side. Therefore, the filtered fluid flows at a higher flow rate on the outer peripheral side, so that the retention of the filtered fluid is suppressed.
