Abstract
A low-temperature sintering ceramic material showing little variation in composition after firing, realizing high bending strength in a sintered body, and capable of forming a reliable ceramic substrate showing high peel strength of a surface electrode includes a main constituent ceramic material containing about 48 weight % to about 75 weight % in terms of SiOof Si, about 20 weight % to about 40 weight % in terms of BaO of Ba, and about 5 weight % to about 20 weight % in terms of AlOof Al, and an accessory constituent ceramic material containing, relative to 100 parts by weight of the main constituent ceramic material, about 2 parts to about 10 parts by weight in terms of MnO of Mn and about 0.1 parts to about 10 parts by weight respectively in terms of TiOand FeOof at least one selected from Ti and Fe, and substantially not includes both Cr oxide and B oxide.
