Ceramic package with brazing material near seal member

Abstract

A ceramic package includes a ceramic substrate, a metallization layer, a first plating layer, a brazing material layer, and a seal member. The ceramic substrate has a surface, and the metallization layer is disposed along an outer periphery of a predetermined region on the surface. The first plating layer is disposed on the metallization layer. The brazing material layer is disposed on the metallization layer with the first plating layer interposed therebetween. The seal member is joined on the metallization layer via the brazing material layer. In at least one of an outer peripheral portion and an inner peripheral portion of the brazing material layer, an end of the brazing material layer is located outside a region directly below the seal member and the end of the brazing material layer is positioned nearer to the seal member than an end of the metallization layer.
