Turbulence of the jet ejected from the nozzle hole is suppressed. The nozzle 100 includes a shaft body 102 having a center axis 127, a liquid guide path 104 located inside the shaft body 102 and extending along the center axis 127, a liquid chamber 106 disposed at a distal end portion of the liquid guide path 104 the liquid chamber 106 having a nozzle hole 108. The nozzle hole 108 is located at the distal end portion of the liquid chamber 106, extending along the ejection axis 122 that extends in a direction different from the center axis 127. The nozzle has an inlet portion 110 having a smaller diameter toward the downstream, and a guide portion 112 connected to the downstream of the inlet portion 110 to guide the liquid to an opening 113.
