WIPO Patent Application WO/2018/122985

A1

This filter is provided with at least a first layer and a second layer. The first layer is located closer to a filtration subject than the second layer is. The first layer is provided with: first components which are arranged so as to extend in a first direction and be apart from each other by a first interval in a second direction intersecting the first direction; and second components which contact upper surfaces of the first components and which are arranged so as to extend in a third direction intersecting the first direction and be apart from each other by a second interval in a fourth direction intersecting the third direction. The second layer includes: third components which are arranged so as to extend in a fifth direction and be apart from each other by a third interval in a sixth direction intersecting the fifth direction; and fourth components which contact upper sections of the third components and which extend in a seventh direction intersecting the fifth direction and be apart from each other by a fourth interval in an eighth direction intersecting the seventh direction. The area size of a single first hole formed in the first layer by the first interval and the second interval is less than the area size of a single second hole formed in the second layer by the third interval and the fourth interval.
