Abstract
A gas header includes a first tubular portion and a second tubular portion that are integrated with each other. The second tubular portion is provided across the first tubular portion from a plurality of flat pipes in the horizontal direction. The second tubular portion is connected at a position midway in an up-down direction and upper than a center of the second tubular portion in the up-down direction to a refrigerant pipe. A wall between the first tubular portion and the second tubular portion has a first hole opening and extending in the horizontal direction at a portion connected to the refrigerant pipe and a second hole through which the first tubular portion and the second tubular portion communicate with each other at a portion lower than the first hole and having a hole diameter smaller than a hole diameter of the first hole.
