The other one first branch channel is different from the at least one first branch channel.

  In the flow divider according to the second aspect of the present invention, the second flow dividing portion does not flow the refrigerant that has entered the other one of the plurality of first flow paths, so that the refrigerant is non-uniformly divided. Can do. Therefore, when the refrigerant entering from the inlet portion is divided unevenly, the inlet portion does not have to be eccentric with respect to the central axis of the flow divider. Thereby, regardless of the flow rate of the refrigerant that has entered the inlet, the refrigerant can be non-uniformly divided.

  The shunt according to the third aspect of the present invention further includes a third shunt. The third diverter divides the refrigerant that has entered at least one second diversion channel among the plurality of second diversion channels into a plurality of third diversion channels.

  When the refrigerant entering from the inlet portion 131 is non-uniformly divided, the inlet portion 131 does not have to be eccentric with respect to the central axis of the flow divider 100. Thereby, regardless of the flow rate of the refrigerant that has entered the inlet portion 131, the refrigerant can be non-uniformly divided.

  In the flow divider 100 of the present embodiment, the second flow dividing portion 134 and the third flow dividing portion 135 are provided on the basic member 130. That is, it is provided on a common member. Therefore, an increase in the number of parts can be suppressed.
