Abstract
A stacking-type header according to the present invention includes: a first plate-shaped unit; and a second plate-shaped unit stacked on the first plate-shaped unit, and having a distribution flow passage, in which the distribution flow passage includes a branching flow passage including: a first flow passage; and a second flow passage, and in which the branching flow passage is smaller in difference in flow resistance between the first flow passage and the second flow passage than a branching flow passage in a state in which a flow-passage resistance in the first flow passage and a flow-passage resistance in the second flow passage are equal to each other, and in a state in which the first flow passage and the second flow passage are point symmetric with each other about the opening port.
