- the pressure loss of the fluid can be suppressed, and the fluid flows from the first flow path to the communication flow path. Then, it can smoothly flow into the second flow path. Further, since the fluid can smoothly flow from the first flow path to the second flow path through the communication flow path, the fluid that has flowed into the second flow path through the communication flow path is changed from the spiral flow path to the branch flow path. Thus, the fluid can be discharged from the fluid outlet earlier than the fluid flowing into the second flow path.
