Abstract
When a ceramic substrate is manufactured through a constraint firing step that uses a constraining layer, the constraining layer is removed without causing significant damage to a sintered base layer or an electrode formed on the surface of the sintered base layer, and the electrode can be reliably exposed. A green stacked body having a base layer and a constraining layer disposed so as to be in contact with at least one principal surface of the base layer is formed. A fired stacked body having a sintered base layer and a green constraining layer is then obtained by firing the green stacked body to sinter the base layer. Subsequently, the constraining layer is removed from the sintered base layer by vibrating media that are disposed so as to be in contact with the constraining layer.
