To provide a beverage feeder in which bacteria or the like propagated in a water purifier and the inside of the pipeline of a beverage unit are allowed to die out and the bacteria or the like allowed to die out are discharged to the outside.

The beverage feeder is equipped with a water supply pipe 10 for supplying raw water such as tap water, a water purifier A which catchs and adsorbs trihalomethane or the like contained in raw water introduced through the water supply pipe 10, a lead-out pipe 15 passing clean water produced in the water purifier A and a beverage unit B for supplying beverage by using clean water sent through the lead- out pipe 15. The water purifier A is provided with an electric heater for heating the caught suspension or the like. In this case, the beverage feeder is constituted of a structure provided with a pipeline sterilization means which discharges hot water produced by the electric heater in the inside of the water purifier A to the outside through the lead-out pipe 15. Thereby, bacteria or the like in the lead-out pipe 15, through which clean water is passed, to say nothing of the inside of the water purifier A are sterilized and discharged to the outside because hot water produced in the inside of the water purifier A is discharged through the lead-out pipe 15 by the pipeline sterilization means.
