Each solution guide includes a support portion of flat-plate shape and a tip end portion of flat-plate shape that is extendingly provided to form a step in a thickness direction in an end portion of the support portion and is thinner than the support portion. An image recording apparatus includes the liquid ejection head and an image corresponding to image data is recorded on a recording medium.
