Patent ID: 7162794

Claim:
A method of manufacturing multilayer ceramic elements comprising the steps of: preparing a multilayer integrated substrate comprising an integrated laminate body including a plurality of ceramic layers and having a main surface, the integrated laminate body including a plurality of multilayer ceramic elements, a plurality of breaking grooves arranged in the main surface in a grid pattern such that respective ones of the plurality of breaking grooves cross one another at intersectional points so as to section the integrated laminate into the plurality of multilayer ceramic elements; and providing at least one fracture-preventing member in the integrated laminate body, the at least one fracture-preventing member being arranged so as to cross at least one of said plurality of breaking grooves and being arranged below the plurality of breaking grooves in the integrated laminate body; and breaking said multilayer integrated substrate along said plurality of breaking grooves into the plurality of multilayer ceramic elements; wherein the multilayer integrated substrate comprises a main portion in which the plurality of multilayer ceramic elements are arranged in a matrix in a plane and a margin portion which surrounds the main portion and defines a region that is closer to a periphery of the multilayer integrated substrate than any of the intersectional points of the plurality of breaking grooves; and the at least one fracture-preventing member is provided in the margin portion of the multilayer integrated substrate at an end of at least one of the plurality of breaking gooves in the region that is closer to the periphery of the multilayer integrated substrate than any of the intersectional points of the plurality of breaking grooves.
