Summary:PROBLEM TO BE SOLVED: To prevent non discharge even if bubbles enter a channel. SOLUTION: An ink supply route 16 is large in cross section, and an ink tank is connected to the top thereof. The ink supply route 17 is semi-circular, and its cross-sectional area is equal to the ink supply route 16 or smaller. Even if bubbles enter that part, they adhere to the upper part and do not flow to lower corners, so a route can be obtained, and the flow of ink is not inhibited. An ink supply route 19 connected to a head tip is small in diameter, bubbles entering the part can be removed by the maintenance of sucking ink forcibly. Bubbles entering an upstream part are not carried to the ink supply route 19 due to a difference in flow velocity due to a difference in cross-sectional area.
