Abstract
In a manufacturing method for a monolithic ceramic electronic component, a plurality of green chips arrayed in row and column directions which are obtained after cutting a mother block are spaced apart from each other and then tumbled, thereby uniformly making the side surface of each of the green chips an open surface. Thereafter, an adhesive is applied to the side surface. Then, by placing a side surface ceramic green sheet on an affixation elastic body, and pressing the side surface of the green chips against the side surface ceramic green sheet, the side surface ceramic green sheet is punched and stuck to the side surface.

A manufacturing method for a monolithic ceramic-electronic component, comprising the steps of:
- preparing a mother block including a plurality of ceramic green sheets that are stacked on each other, and an internal electrode pattern arranged along each of a plurality of interfaces between the ceramic green sheets;
- performing a first cutting including cutting the mother block along a first cutting line to obtain a plurality of rod-shaped green block bodies, the rod-shaped green block bodies each having a laminated structure including a plurality of ceramic layers and a plurality of internal electrodes that are in a raw state, the internal electrodes being exposed on a cut side surface that is produced by the first cutting along the first cutting line;
- affixing a side surface ceramic green sheet to the cut side surface to form a raw ceramic protective layer;
- performing a second cutting including cutting each of the rod-shaped green block bodies along a second cutting line extending in a direction perpendicular or substantially perpendicular to the first cutting line to obtain a plurality of raw component bodies that are each a component body in a raw state;
- firing the plurality of raw component bodies;
- and
- applying an adhesive between the side surface ceramic green sheet and the cut side surface, the step of applying the adhesive being performed on the plurality of raw component bodies or on the side surface ceramic green sheet.
