PURPOSE: To make electronic parts to normally and stably operate for a long period by preventing the scattering and adhesion of solder used as a sealing material to electronic parts housed in the title package.
CONSTITUTION: A first metallic layer 8 with which an insulating substrate 1 is coated and second metallic layer 9 with which a cap body 2 is coated are prevented from being exposed in the space of the title package for housing electronic parts. In addition, either one of the layers 8 and 9 is provided 0.2mm apart from the space for housing electronic parts. Because of this distance, partial scattering of a sealing material 10 inside the container 4 composed of the substrate 1 and cap body 2 through the layers 8 and 9 and malfunctions of the electronic parts caused by the material 10 adhering to the parts can be prevented when the cap body 2 is joined to the substrate 1 with the material 10 and the electronic parts are airtightly sealed in the container 4. Therefore, the electronic parts can be made to normally and stably operate for a long period.
