摘要：
A conventional lapping process of executing element size control and surface roughness reduction at the same time is divided in the present invention into a lapping process for element size control and a lapping step for surface roughness reduction. In the lapping process for surface roughness reduction, a surface of a ceramic substrate portion is used as a stopper for limiting cut-in of abrasive grains to realize surface roughness reduction while maintaining productivity.
