Abstract
This invention provides a method of producing a ceramic laminate body capable of suppressing the occurrence of de-lamination and cracks, and providing high reliability. This method comprises a heat-bonding step of covering a full periphery of side surfaces of ceramic layers 11 positioned in an orthogonal direction to a laminating direction with a side surface jig while the ceramic layers are laminated, heating the ceramic layers and pressing the ceramic layers from both end faces positioned in the laminating direction by end face jigs to form a heat-bonded ceramic laminate body; and a side surface grinding step of grinding or cutting the full periphery of the side surfaces inclusive of damage portions 9 occurring in the ceramic laminate body in the heat-bonding step.
