Abstract:
1. A collector which receives a gas, and collects a material in the gas, comprising: a first hole portion that is open at a first end on a side for receiving the gas, and is closed at a second end on a side opposite to the first end; and a second hole portion that is closed at the first end, and is open at the second end, wherein: the first hole portion and the second hole portion are adjacent to each other; a partition wall which partitions between the first hole portion and the second hole portion adjacent to each other is an partition wall which is easy for the gas to pass through or a partition wall which is hard for the gas to pass through; and the material in the gas is collected by the partition wall when the gas passes through the partition wall, wherein a line segment, which is an intersection portion of a line perpendicular to an extension direction of the first and second hole portions and the collector, passes through the first hole portion adjacent to the second hole portion via only the partition wall which is hard for the gas to pass through and the second hole portion adjacent to the first hole portion via only the partition wall which is hard for the gas to pass through, and does not pass through the first hole portion adjacent to the second hole portion via the partition wall which is easy for the gas to pass through and the second hole portion adjacent to the first hole portion via the partition wall which is easy for the gas to pass through.
