1. A distributor comprising:
an upstream flow path extending in a first direction; and
a downstream flow path located downstream of the upstream flow path in a refrigerant flow,
the downstream flow path having
a branch portion having a first connecting portion connected to the upstream flow path to branch the refrigerant flow from the first connecting portion in a second direction intersecting the first direction,
a bent portion having a second connecting portion connected to the branch portion, the bent portion being located downstream of the branch portion in the refrigerant flow,
the second connecting portion of the bent portion being located downstream of the first connecting portion of the branch portion in the refrigerant flow,
the upstream flow path has
a first width of a portion disposed upstream of the first connecting portion in the refrigerant flow, and
a second width of a portion connected to the first connecting portion,
the upstream flow path is configured to decrease from the first width to the second width,
the upstream flow path has a tapered shape continuously decreasing from the first width to the second width, and
the tapered shape extends to and terminates at the first connecting portion,
wherein in the second direction, a length between the first connecting portion and the second connecting portion is greater than or equal to a dimension obtained by multiplying a width of the branch portion in the first direction by tan 15°.
