A liquid supply device includes a container, a boring part, an operation lever, a fixing member, and a coupling portion. The container includes a sealing film and is filled with a liquid. The boring part bores the sealing film of the container when the boring part is inserted into the container to discharge the liquid from the container and supply the liquid to a supply destination. The operation lever is connected to the boring part and operates the boring part so that the boring part is pulled out and inserted into the container. The fixing member fixes the operation lever when the boring part is inserted into the container. The coupling portion is installed in the container and is coupled with the operation lever when the operation lever is moved to the position where the boring part is inserted into the container to prevent the boring part from slipping.
