Abstract
A laminate includes base material layers and interlayer constraining layers disposed therebetween. The base material layers are formed of a sintered body of a first powder including a glass material and a first ceramic material, and the interlayer constraining layer includes a second powder including a second ceramic material that will not be sintered at a temperature for melting the glass material, and is in such a state that the second powder adheres together by diffusion or flow of a portion of the first powder including the glass material included in the base material layer at the time of baking. The incorporated element is in such a state that an entire periphery thereof is covered with the interlayer constraining layer.
