Refrigerant distributor, heat exchanger, and refrigeration cycle device

A refrigerant distributor that is provided in a heat exchanger that includes a plurality of heat transfer pipes, and that distributes a refrigerant comprises:

• a first pipe;
• and
• a second pipe that is connected to the first pipe;
• wherein
• the second pipe has
• a pair of parallel pipes that extend in the first direction, and are arranged in a second direction that intersects the first direction, having intervals therebetween, and
• a linkage pipe that connects each end in the first direction, of the pair of parallel pipes to one another,
• the first pipe has
• a first extension pipe that extends in the second direction,
• a second extension pipe that bends and extends from the first extension pipe,
• a third extension pipe that bends and extends to the second direction from the second extension pipe, and connects to one of the pair of parallel pipes,
• the second extension pipe bends to one side in a direction that is orthogonal to both the first direction and the second direction, with respect to the first extension pipe,
• each of the pair of parallel pipes is connected to two heat transfer pipes, out of the plurality of heat transfer pipes, that differ from one another, and
• the refrigerant distributor distributes the refrigerant that flows to an inside of the first pipe, to the two heat transfer pipes, by causing the flow to diverge so as to become two flows in the second pipe.
