摘要：
A laminated body has a substrate and a metallic layer. The substrate is composed of an inorganic material. The metallic layer is disposed on the substrate. One of the substrate and the metallic layer has a main body portion and a plurality of protruding portions. The protruding portions are formed on the main body portion. The protruding portions are embedded in the other of the substrate and the metallic layer. An outer diameter of each of the protruding portions is configured to decrease towards the main body portion.
