Abstract
A holding apparatus includes a holding substrate that has a first surface and a second surface opposite the first surface. The holding substrate includes a plate member that contains a ceramic as a main component. An electrode layer is disposed in the plate member. The electrode layer contains a conductive material as a main component and a ceramic as a sub-component. The plate member includes a first dielectric layer disposed on a surface of the electrode layer facing the first surface and in which a content of the main component is 99% by mass or more, and a second dielectric layer disposed on a surface of the electrode layer facing the second surface and in which a content of the main component is 99% by mass or more. A fractal dimension of the surface of the electrode layer facing the first surface is 1.18 or more.
