PURPOSE:To provide a ceramic substrate from which small multiple pieces can be obtained in a collective manner. CONSTITUTION:At least on one main surface of a large area type flat plate shape ceramic substrate 1, dividing grooves 2 are formed so that the ceramic substrate 1 is divided into plural sections, a multiple-piece ceramic substrate thus constituted. The dividing grooves 2 at the outer peripheral part of the ceramic substrate 1 are shallower than those at the central part. When semiconductor elements, registors, etc., are mounted on sections of the ceramic substrate 1 using an automatic machine, cracks will not be formed on the ceramic substrate 1 even if external force is applied to the ceramic substrate 1 by the automatic machine. So, semiconductor elements, registors, etc., are precisely mounted on the sections of the ceramic substrate 1. |
