An ink-jet recording apparatus includes a recording head, an ink channel supplying the recording head with ink and a valve body controlling the supply of ink to the recording head in the ink channel. The ink channel has a valve accommodation room and a valve opening formed in a wall surface located at one end of the valve accommodation room. In an ordinary state the valve body is urged to be in contact with the wall surface and to close the valve opening. In that state, a first area of the valve body, on which a pressure in a direction of opening the valve body from the valve opening acts, is smaller than a second area of the valve body, which is on an opposite side to the first area and on which a pressure within the valve accommodation room acts.
