Mist blower and manufacturing method of liquid nozzle

A manufacturing method of a liquid nozzle configured to introduce liquid stored in a liquid tank into an ejection tube through which air flows,

• wherein
• the liquid nozzle comprises:
• a base body including a penetrating aperture which extends in a first direction and through which the liquid flows;
• and
• a press-in body configured to be press-fitted in the base body,
• the penetrating aperture comprises:
• a constricted part having a minimum diameter in the penetrating aperture;
• a first aperture part having a diameter greater than the diameter of the constricted part;
• and
• a second aperture part disposed opposite to the first aperture part with respect to the constricted part and having a diameter greater than the diameter of the constricted part,
• the manufacturing method comprises:
• press-fitting the press-in body into the second aperture part to a position that is a predetermined distance away from the constricted part;
• and
• after the press-fitting, cutting the base body in a second direction perpendicular to the first direction at a position between the constricted part and the press-in body to define an opening penetrating the base body from a side surface of the base body to an inner surface of the base body.
