Zusammenfassung:To provide at least one of a sintered body and a method for producing the same, which has excellent mechanical strength and translucency.SOLUTION: The present invention is a sintered body having zirconia as a matrix in which a stabilizing element and lanthanum are dissolved. A content of the stabilizing element is 8 mol% or more and 12 mol% or less, and the biaxial bending strength is 500 MPa or more. The lanthanum content is preferably 1 mol% or more and 10 mol% or less.SELECTED DRAWING: Figure 2 【課題】本発明は、優れた機械的強度及び透光性を兼備する、焼結体及びその製造方法の少なくともいずれかを提供する。【解決手段】本発明は、安定化元素及びランタンを固溶したジルコニアをマトリックスとした焼結体であって、前記安定化元素の含有量が８ｍｏｌ％以上、１２ｍｏｌ％以下であり、二軸曲げ強度が、５００ＭＰａ以上である、焼結体である。また、本発明は、ランタン含有量が１ｍｏｌ％以上、１０ｍｏｌ％以下であることが好ましい。【選択図】図２
