Abstract
A refrigerant distributor includes an outer pipe, an inner pipe, and a structural part. The refrigerant outflow hole is provided such that an angle θ between a lower end of the inner pipe on a vertical line passing through a center of the inner pipe and a position of presence of the refrigerant outflow hole as seen from the center of the inner pipe falls within a range of 10 degrees≤θ≤80 degrees. The refrigerant outflow hole comprises a sole refrigerant outflow hole provided in a vertical cross-section of the inner pipe at a position where the refrigerant outflow hole is provided.
