To simplify works for excluding bubbles executed on changing a cartridge while preventing adhesive from being wasted until the bubbles are excluded, and to reduce total cost for an adhesive supply apparatus.

A bubble excluding device 1 to be arranged at the middle of a liquid agent supply line for excluding bubbles K from liquid agent A in a specified viscosity is equipped with a container 2 having a space enclosed with aslant inner faces 8, a stopper body 9 that is detachably attached, and a base 3, a supply pipe 7 that supplies in overflowing the liquid agent to the space, and an outflow pipe 12 that makes the liquid agent outflow. The opening of the supply pipe 7 is placed at a position sufficiently higher than the opening of the outflow pipe.
