A printing apparatus includes: an ink discharge head that discharges UV ink; a sub-tank that stores the UV ink; a forward circulation path through which the UV ink flowing out from the sub-tank to the ink discharge head flows; an inflow path through which the UV ink flowing into the sub-tank flows; and a receptacle that is provided inside the sub-tank and blocks bubbles contained in the UV ink flowing into the sub-tank from the inflow path, from entering the forward circulation path.
