A refrigerant distributor branching refrigerant flowing in a refrigerant circuit into three, comprising: a first bifurcate flow divider including a first pipe portion forming one inflow port at a lower end, a second pipe portion and a third pipe portion forming two outflow ports (52, 53) communicating with the inflow port of the first pipe portion, at upper ends; and a second bifurcate flow divider including a fourth pipe portion forming one inflow port at a lower end, and a fifth pipe portion and a sixth pipe portion forming two outflow ports (55, 56) communicating with the inflow port of the fourth pipe portion, at upper ends, the outflow port of the third pipe portion and the inflow port of the fourth pipe portion communicating with each other, an angle θ formed by a first plane passing through a center point of each of the one inflow port and the two outflow ports (52, 53) of the first bifurcate flow divider and a second plane passing through a center point of each of the one inflow port and the two outflow ports (55, 56) of the second bifurcate flow divider being 60 degrees or more and 120 degrees or less, characterised by: a connection pipe having an upper end connecting to the fourth pipe portion vertically upward, and a lower end connecting to the third pipe portion, wherein the connection pipe includes at least one first curved pipe portion turning from upward to downward in a direction of gravity, and at least one second curved pipe portion turning from downward to upward in the direction of gravity, in a refrigerant flowing direction, a first straight pipe portion located between the first bifurcate flow divider and the at least one first curved pipe portion, and connecting to the third pipe portion, and a second straight pipe portion located between the second bifurcate flow divider and the at least one second curved pipe portion, and connecting to the fourth pipe portion. a first bifurcate flow divider including a first pipe portion forming one inflow port at a lower end, a second pipe portion and a third pipe portion forming two outflow ports (52, 53) communicating with the inflow port of the first pipe portion, at upper ends; and a second bifurcate flow divider including a fourth pipe portion forming one inflow port at a lower end, and a fifth pipe portion and a sixth pipe portion forming two outflow ports (55, 56) communicating with the inflow port of the fourth pipe portion, at upper ends, the outflow port of the third pipe portion and the inflow port of the fourth pipe portion communicating with each other, an angle θ formed by a first plane passing through a center point of each of the one inflow port and the two outflow ports (52, 53) of the first bifurcate flow divider and a second plane passing through a center point of each of the one inflow port and the two outflow ports (55, 56) of the second bifurcate flow divider being 60 degrees or more and 120 degrees or less, characterised by: a connection pipe having an upper end connecting to the fourth pipe portion vertically upward, and a lower end connecting to the third pipe portion, wherein the connection pipe includes at least one first curved pipe portion turning from upward to downward in a direction of gravity, and at least one second curved pipe portion turning from downward to upward in the direction of gravity, in a refrigerant flowing direction, a first straight pipe portion located between the first bifurcate flow divider and the at least one first curved pipe portion, and connecting to the third pipe portion, and a second straight pipe portion located between the second bifurcate flow divider and the at least one second curved pipe portion, and connecting to the fourth pipe portion. a connection pipe having an upper end connecting to the fourth pipe portion vertically upward, and a lower end connecting to the third pipe portion, wherein the connection pipe includes at least one first curved pipe portion turning from upward to downward in a direction of gravity, and at least one second curved pipe portion turning from downward to upward in the direction of gravity, in a refrigerant flowing direction, a first straight pipe portion located between the first bifurcate flow divider and the at least one first curved pipe portion, and connecting to the third pipe portion, and a second straight pipe portion located between the second bifurcate flow divider and the at least one second curved pipe portion, and connecting to the fourth pipe portion.
