Abstract
In an inkjet recording apparatus, a suction channel is defined between a concave groove-like channel of an ink guide member and a cap member. An ink discharge port is open to the suction channel while the suction channel communicates with the atmosphere through a plurality of communication holes. The distance between a bottom surface of the cap member and a surface of the concave groove-like channel facing the bottom surface is reduced in accordance with the distance from the ink discharge port. The ink discharge port is entirely covered with one longitudinal end portion of the ink guide member. The horizontal sectional area of each communication hole increases in accordance with the distance from the ink discharge port.
