Liquid ejecting head manufacturing method and liquid ejecting head

摘要

Precise positioning of a film used to seal an electrical connection on a liquid ejecting head is made possible. Specifically, positioning is conducted in a state in which part of the film is held to a finger by suction. Next, the finger is moved downward while in the positioned state, and part of the film is pressed against a wiring board. With part of the film fixed to the wiring board in this way, a sealing resin flows while being covered by the film. Consequently, shifting of the position of the film as the sealing resin flows may be prevented. As a result, it becomes possible to conduct covering with the film in a precisely positioned state.
