A printing apparatus includes: an ink discharge head discharging UV ink; a sub-tank storing the UV ink; a supply pump sending the UV ink to the sub-tank from an ink cartridge; an ink circulation path having a forward circulation path through which the UV ink supplied to the ink discharge head from the sub-tank flows, and a backward circulation path through which the UV ink returning to the sub-tank from the ink discharge head flows; and a receptacle that has an opening opened upward and is provided inside the sub-tank. Here, a backward-path downstream-side end which is an end portion of the backward circulation path on the sub-tank side is positioned below the opening inside the receptacle and a forward-path upstream-side end which is an end portion of the forward circulation path on the sub-tank side is positioned below the receptacle inside the sub-tank.
