Patent ID: 8764166

Claim:
A liquid ejecting head comprising: a main liquid ejecting head body, in which a liquid flow channel, through which a liquid flows, is disposed, wherein the main liquid ejecting head body ejects the liquid from a nozzle opening using a pressurizing unit; a driving board configured so as to supply power to the pressurizing unit, wherein the driving board is bent into a shape with: at least one extremity extending away from one end surface of the main liquid ejecting head body, and a first portion transverse to the extremity and adjacent the end surface of the main liquid ejecting body; a connector provided at an end portion of the extremity of the driving board; a holding member that holds the driving board in the bent state, wherein the holding member comprises a fastener that holds a region of the driving board adjacent the connector; and a liquid introduction unit, disposed on the one end surface of the main liquid ejecting head body, comprising: a liquid introduction channel that introduces the liquid into the liquid flow channel; a driving board passage portion that is open at the top and bottom; an exposure portion that exposes the connector from an upper opening of the driving board passage portion when the holding member and the driving board held by the holding member have been inserted into the driving board passage portion; a restricting portion configured to restrict the position of the connector by making contact with the connector at the inner wall of at least the upper opening of the driving board passage portion, wherein the restricting portion is tapered, so that the surface area of the opening of the restricting portion decreases as the opening progresses toward the upper opening, such that, during insertion of the driving board and the holding member into the liquid introduction unit, the restriction portion compresses the driving board; and a groove in the inner wall of the driving board passage portion which matches the shape of the fastener, configured to provide clearance for the fastener during the insertion of the driving board and the holding member into the liquid introduction unit.
