Abstract: A filtration filter having a planar shape and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction and extends in a second direction along at least a first portion of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.

Abstract: A filtration device that includes: a passage member defining a passage including an inlet and an outlet; and a filter disposed in the passage between the inlet and the outlet. The inlet has an inlet passage sectional area. The passage includes a first passage having a first passage sectional area that increases from the inlet toward the filter on an upstream side of the filter, and a second passage having a second passage sectional area that is uniform from the first passage toward the filter. The second passage sectional area is greater than the first passage sectional area, and a second passage length of the second passage is greater than a first passage length of the first passage.
