Abstract

　結晶核が残存し特定元素を所定濃度範囲で含む結晶面に沿って少なくとも一部が層状である第１領域と、この第１領域と異なる濃度範囲でこの特定元素を含む結晶面に沿って少なくとも一部が層状である第２領域とが交互に繰り返されることにより、結晶面に対して直交する方向に組成分布を有しており、この組成分布が、Ｎａの濃度が第２領域よりも高くＫの濃度が第２領域よりも低くＮｂの濃度が第２領域よりも低くＴａの濃度が第２領域よりも高い領域である第１領域と、Ｎａの濃度が第１領域よりも低くＫの濃度が第１領域よりも高くＮｂの濃度が第１領域よりも高くＴａの濃度が第１領域よりも低い領域である第２領域と、が交互に繰り返されることにより形成されている。
