<P>PROBLEM TO BE SOLVED: To provide a thermal expansion suppressing member having negative thermal expansion properties and a metal-based anti-thermally-expansive member having a small thermal expansion. <P>SOLUTION: The thermal expansion suppressing member includes at least an oxide represented by the following general formula (1), and the anti-thermally-expansive member includes a metal having a positive linear expansion coefficient at 20°C, and a solid body including at least an oxide represented by the following general formula (1), the metal and solid being joined to each other: (Bi<SB POS="POST">1-x</SB>M<SB POS="POST">x</SB>)NiO<SB POS="POST">3</SB>(1) where M represents at least one metal selected from the group consisting of La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Y, and In; and x represents a numerical value of 0.02≤x≤0.15. <P>COPYRIGHT: (C)2012,JPO&INPIT |
