Mother ceramic substrate, ceramic substrate, mother module component, module component and method for manufacturing mother ceramic substrate

摘要

It is possible to divide the divided end faces so that the divided end faces are perpendicular to the main faces of individual substrates when divided into individual substrates (ceramic substrates), and it is possible to obtain a ceramic substrate with high shape accuracy A mother ceramic substrate, an individual ceramic substrate obtained from the mother ceramic substrate, a module component including the ceramic substrate, and a method of manufacturing a mother ceramic substrate. A dividing groove 3 for defining a dividing position is formed on one main surface 2a of a mother ceramic substrate 1 configured so as to be divided at a predetermined position and divided into a plurality of individual substrates, When viewed from the thickness direction of the mother ceramic substrate 1 on the main surface 2 b, the ridge 4 is formed at a position corresponding to the position where the dividing groove 3 of the one main surface 2 a is formed. The internal conductors are arranged in such a manner that individual substrates (ceramic substrates) 31 obtained after division each have internal conductors.
