发明名称 Liquid ejecting head and liquid ejecting apparatus
摘要 A liquid ejecting head includes: a main head unit that ejects ink; a first flow channel member and a second flow channel member that include first and second flow channels, respectively, through which ink to be supplied to the main head unit flows; and a ring-shaped sealing member pinched by the first flow channel member and the second flow channel member. The first flow channel and the second flow channel communicate with the interior of a space area defined by the first flow channel member, the second flow channel member, and the sealing member, and an atmosphere exposure channel that connects the space area with the exterior is formed in a joining surface between the sealing member and the first flow channel member.
