Abstract
The liquid ejecting head includes a printing element board having a plurality of printing elements for producing energy used to eject liquid, a contact board having a contact terminal for electrically connecting to a liquid ejection printing apparatus, and a functional element, and a plurality of lands which are provided on a face of the contact board where the functional element is mounted, and to which terminals of the functional element are connected. In addition, a wiring member connects the printing element board to the contact board, a first terminal is configured to be electrically connected to the printing element board, and a second terminal is configured to not be electrically connected to the printing element board, with both terminals disposed on one edge of the contact board. A first wiring connects the contact terminal to the first terminal, a second wiring connects at least one of the plurality of lands to the second terminal, and insulating resin covers an edge face of the second terminal positioned on the one edge of the contact board.
