Abstract
A sheet substrate for use in manufacturing surface-mount crystal oscillators has a plurality of container bodies fabricated thereon. Each of the container bodies is capable of accommodating at least one IC chip, and has a bottom face formed with a plurality of mount terminals and a top face which is capable of forming a crystal unit thereto. On the sheet substrate, each of the container bodies has a conductive path extending from the container body to an adjacent container body and connected to a mount terminal of the adjacent container body, and a chip carrying terminal connected to one end of the conductive path for use in electric connection with the IC chip.
