摘要

PROBLEM TO BE SOLVED: To provide a substrate for an electronic device which provides a long life and high reliability electronic device where wiring exfoliation or deterioration is suppressed, by embedding wiring therein while maintaining surface smoothness.SOLUTION: A substrate 100 for an electronic device including first and second opposite main surfaces and having electrode wiring formed on the first main surface includes a glass substrate 101, an auxiliary wiring pattern 200 formed on the first main surface of the glass substrate 101, and a translucent glass layer 102 formed on the surface of the glass substrate 101 so as to overlie the auxiliary wiring pattern 200. Through holes H exposing the auxiliary wiring pattern 200 are formed in part of the glass layer 102, and the entire auxiliary wiring pattern 200 is sealed in the glass layer 102 except for connecting areas exposed through the through holes H. The glass layer vitrified has a smooth surface, and an overlying functional layer is further formed.
