Abstract
An electronic component having recesses on side faces of its package for housing an electric element therein. A metal layer that does not reach the bottom end of the package is formed on the surface of the recess. The metal layer has excellent wettability to a brazing material and helps extra material flow into the recess easily. In addition, the interface between the top end face of the recess and the side face is curved to make the brazing material flow into the recess easily. When the opening of the package is sealed with a lid using the brazing material, the extra brazing material flows into the recess. This prevents the brazing material from protruding outside of the package and thus improves dimensional accuracy of the electronic component. Therefore, mounting accuracy of the electronic component can be improved and short circuit can be prevented.
