A manufacturing method for a monolithic ceramic part permitting a ceramic laminate to be cut stably and speedily, even if the thickness of the ceramic laminate is large. In order to divide a mother ceramic laminate into individual laminates of monolithic ceramic part units, the ceramic laminate is cut with a cutting blade, using a pair of guides disposed on opposite sides of the cutting blade in the vicinity of one principal plane of the ceramic laminate to control the cutting direction, and then individual ceramic laminates thus obtained by cutting are fired.
