<p>There is provided 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. A low-temperature sintering ceramic material used for constituting a ceramic layer (2) of a multilayer ceramic substrate (1) includes a main constituent ceramic material containing 48 to 75 weight% in terms of SiO 2 of Si, 20 to 40 weight% in terms of BaO of Ba, and 5 to 20 weight% in terms of Al 2 O 3 of Al, and an accessory constituent ceramic material containing, relative to 100 parts by weight of the main constituent ceramic material, 2 to 10 parts by weight in terms of MnO of Mn and 0.1 to 10 parts by weight respectively in terms of TiO 2 and Fe 2 O 3 of at least one selected from Ti and Fe, and substantially not includes both Cr oxide and B oxide.</p> |
