BONDING METHOD, BONDED BODY, LIQUID JETTING HEAD AND LIQUID JETTING DEVICE

摘要

A bonding method is provided with a step of forming plasma-polymerized films on the surfaces of the two base materials, respectively; a step of activating each surface by selectively applying ultraviolet to a prescribed region of a part of the surface of each plasma-polymerized film; and a step of obtaining a bonded body by bonding the two base materials to have the activated regions on the surfaces of the plasma-polymerized films adhere to each other and by partially bonding the two base materials at the portion where the ultraviolet applied region of one plasma-polymerized film overlaps with the ultraviolet applied region of the other plasma-polymerized film.
