Abstract:
A printer for performing a printing operation in which ink drops are caused to fly out of a printer head as a result of driving of a heating element disposed in the printer head, the printer comprising:the printer head wherein predetermined lamination materials are successively placed upon each other on a semiconductor substrate of a semiconductor device in order to form the heating element, the heating element being formed at a top side of multiple layers of wiring patterns to form a resistance film, a drive circuit which drives the heating element, a wall surface of an ink chamber which holds ink so that the ink is heated by the heating element, and another wall surface of an ink path used to guide the ink to the ink chamber; wherein a predetermined plate-shaped material is disposed in order to form the ink chamber, the ink path, and a nozzle, the nozzle being used to guide the ink in the ink chamber to the outside, and at least one of the lamination materials placed upon each other on the semiconductor substrate is smooth so that a surface where the plate-shaped material is to be disposed is smooth.
