The casing has a frame wall which defines the recess. The IC chip has an outer peripheral edge joined to an upper surface of the frame wall. The crystal blank is hermetically sealed in a space surrounded by the casing and the IC chip. IC connecting terminals are disposed on the upper surface of the frame wall for connection to IC terminals on the IC chip.
