Provided is a liquid supply system that achieves an improvement in pump function. The invention is provided with a first bellows (41) and second bellows (42) which are arranged in series in an expansion/contraction direction in a container (12) interior, and in which first end portions on the sides that are adjacent to each other are fixed to the inner wall of the container (12), and second end portions on the sides that are distant from each other are configured to be movable in the expansion/contraction direction, wherein the portion of the container (12) to the outside of the first bellows (41) is a first pump chamber (P1), the portion to the outside of the second bellows (42) is a second pump chamber (P2), and the portion to the inside of the first bellows (41) and second bellows (42) is a sealed space (R1), and the first bellows (41) and second bellows (42) expand/contract due to the reciprocal movement of a shaft (15) to which the second end portions are fixed. |
