CONTROL SUBSTRATE, AND MANUFACTURING METHOD OF THE CONTROL SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a control substrate having a highly reliable switching element having a high adhesive feature of a member formed on a substrate body, and to provide a control substrate manufacturing method for inexpensively manufacturing the control substrate. SOLUTION: An undercoat layer 26 is arranged on one surface of the substrate body 25, and first and second gate electrodes 34 and 41 are formed on one surface in the thickness direction Z of the undercoat layer 26 by an coating method. The undercoat layer 26 is formed of a member having an adhesive feature with an electrode such as the first and second gate electrodes 34 and 41 higher than an adhesive feature between the electrode and the substrate body when forming the electrode on the one surface of the substrate body 25 by the coating method.
