The inventors have newly found that, even when a composition of a first element body portion and a composition of a second element body portion are different from each other, a high bonding strength at an interface between the first element body portion and the second element body portion can be obtained when both the first element body portion and the second element body portion contain Zn.sub.2SiO.sub.4 as a constituent component. That is, when the first element body portion and the second element body portion contain Zn.sub.2SiO.sub.4, a bonding strength at the interface is improved compared to a case in which the first element body portion and the second element body portion do not contain Zn.sub.2SiO.sub.4.
