• a rotation member configured to hold the connecting member such that a posture of the connecting member is changeable, and configured to be supported by the support member to be rotatable between a connecting position at which the ink introduction portion and the connecting portion are connected and a connection releasing position at which the ink introduction portion and the connecting portion are not connected;
• and
• a biasing portion configured to bias the connecting member to a first posture with respect to the rotation member,
• wherein the printhead includes an upper surface on which the ink introduction portion is provided,
• the upper surface includes a first end and a second end opposite to the first end,
• the first end is closer to a rotation center of the rotation member than the second end is to the rotation center, and
