Abstract:
A device (2) is formed on a main surface of a substrate (1). The main surface of the substrate (1) is bonded to the undersurface of the counter substrate (14) via the bonding member (11,12,13) in a hollow state. A circuit (17) and a bump structure (26) are formed on the top surface of the counter substrate (14). The bump structure (26) is positioned in a region corresponding to at least the bonding member (11,12,13), and has a higher height than that of the circuit (17).
