A beverage dispenser configured such that, when the beverage dispenser uses a soft, raw water container, drinking water in the container can be smoothly and entirely consumed. The inside of a water passage tube (12) of a container connecting section (10) is partitioned by a tubular partition wall (13) into a water passage section (14) having a water passage hole (14a) formed therein and allowing a water passage tube (16) to be connected thereto and into an air passage section (15) having formed therein a small air passage hole (15a) open in the water passage section (14). An air passage pipe (17) suspended into a low-temperature tank (2) is connected to an opening (15b) in a base (12a) which opening (15b) communicates with the air passage section (15). An on-off valve (19b) opened when the level of water in the low-temperature tank (2) descends is connected to the front end of the air passage pipe (17). When the amount of drinking water remaining in a raw water container (A) becomes less to cause the level of the water in the low-temperature tank (2) to be held constant at a low level, air in the low-temperature tank (2) is introduced into the raw water tank (A) through the small air passage hole (15a) connecting from the air passage pipe (17), which is opened by the on-off valve (19b), to the air passage section (15). This cancels negative pressure in the raw water container (A) to allow the remaining drinking water to drop.
