ABSTRACT:
A method of producing ceramics base plates is disclosed, comprising forming a continuous flaw on at least one surface of a ceramics sintered base plate from end to end using a flawing tool and dividing the ceramics sintered base plate along the flaw by applying an external force. It is preferred that a blade edge portion of the flawing tool is made of a cemented carbide or diamond. By the method of the invention, the ceramics sintered base plate can be easily divided, and ceramics base plates excellent in dimensional accuracy are obtained without lowering the strength thereof.
