PURPOSE: To prevent bacteria from proliferation by completely heating liquid remaining at the inside of a nozzle, removing it even if the liquid remains inside a nozzle by providing a heater for heating the internal face of the nozzle.

CONSTITUTION: An insertion port 10a to be inserted in the ejecting port of a main body is formed at the upper part of the ejecting nozzle 10 and a nozzle face 10c whose diameter is a little narrow is formed at the lower part of the insertion port 10a. A carbonated water or water provided from the delivery port of the main body is abutted on the nozzle face 10c and drops down as a mixed liquid while being mixed with syrup and a mixed liquid ejecting port 10b is provided on the lower part of the ejecting nozzle 10. Furthermore, the heater 11 is buried in the side wall to heat the nozzle face 10c and the heater 11 is constituted by holding a PTC element therebetween by a flat terminal 12 and a spring terminal 13. Thus, by applying voltage between the flat terminal 12 and the spring terminal 13, the PTC element and the nozzle face 10c are heated.
