Abstract

A ring-like sealing frame () and a bump () are simultaneously formed on a main surface of a first substrate () by patterning a metal paste. A ring-like protrusion () having a smaller width than a width of the sealing frame () is formed on a main surface of a second substrate (). The main surface of the first substrate () and the main surface of the second substrate () are aligned to face each other. The sealing frame () is bonded to the protrusion (), and the bump () is electrically bonded to the second substrate (). A height of the protrusion () is 0.4 to 0.7 times a distance between the first substrate () and the second substrate () after bonding.
