Claim:
A method for manufacturing a multilayer ceramic board, comprising the steps of: disposing on at least one principal surface of a layered body including a plurality of board ceramic green sheets including ceramic material powder, a contraction prevention green sheet including inorganic material powder which is not sintered at a baking temperature of said board ceramic green sheets to form a compound layered body; baking said compound layered body under a condition in which said ceramic material powder is sintered, and said inorganic material powder is not sintered; and removing from said baked compound layered body said contraction prevention green sheet which has not been sintered; wherein said disposing step includes a step of disposing said contraction prevention green sheet such that along at least a portion of an outer circumference of a surface of said board ceramic green sheet of said layered body that is in contact with said contraction prevention green sheet, said portion and a nearby portion thereof are not directly in contact with said contraction prevention green sheet; and in said baking step, a protruding portion which protrudes in a vertical direction of said principal surface is formed at said portion and said nearby portion.
