CERAMIC SUBSTRATE, COMPOSITE SUBSTRATE, CIRCUIT BOARD, METHOD FOR PRODUCING CERAMIC SUBSTRATE, METHOD FOR PRODUCING COMPOSITE SUBSTRATE, METHOD FOR PRODUCING CIRCUIT BOARD, AND METHOD FOR PRODUCING PLURALITY OF CIRCUIT BOARDS
A ceramic substrate of the present invention is a ceramic substrate having a rectangular shape in a plan view, in which, at a location deviating from an intersection formed by a pair of diagonal lines of the ceramic substrate, at least one convex portion that is convex toward one side or the other side in a sheet thickness direction is formed, and a value obtained by dividing a maximum projection amount of the at least one convex portion by a length of the diagonal line of the ceramic substrate is equal to or less than 2 µm/mm.
