Dielectric porcelain material.

摘要

Disclosed are dielectric porcelain materials having compositions falling in the quadrilateral area defined by connecting points A, B, C and D in the ternary diagram of components Al<Sub>2</Sub>O<Sub>3</Sub>, CaTi0<Sub>3</Sub> and SrTiO<Sub>3</Sub> in the drawing. The points A, B, C and D are represented in mol% as follows:
