ABSTRACT:
In a wiring substrate having a metal wiring pattern that is formed on a substrate and includes a contact portion for providing connection to an external element, an organic thin film containing silane is formed to cover the metal wiring pattern and the contact portion is electrically connected to the external element through the organic thing film. Unlike conventional wiring substrates in which a contact portion is uncovered by ripping open or cutting away a protective resin film formed on the contact portion, the wiring substrate can be electrically connected with an external element having a low contact pressure, for example.
