<P>PROBLEM TO BE SOLVED: To provide an electrode substrate capable of reducing resistance of the electrode substrate, and suppressing deterioration in characteristics caused by electrical leak from metal wiring to an electrolyte and corrosion of a metal wiring layer. <P>SOLUTION: The electrode substrate 1 is formed by laminating a transparent conductive layer 11, a metal wiring layer 12, and an insulating layer 14 covering the metal wiring layer on a substrate 10 in order, and when the coefficient of thermal expansion of the substrate is defined as α and the coefficient of the thermal expansion of the insulating layer is defined as β, a value of β divided by α is made 0.5 to 18. <P>COPYRIGHT: (C)2008,JPO&INPIT |
