A low temperature sinterable dielectric ceramic composition, as well as a multilayer ceramic chip capacitor and a ceramic electronic device. The dielectric ceramic composition comprises a major composition represented by the general formula: x{&#x3b1;BaO, (1&#x2212;&#x3b1;)SrO}-y{SiO}-z{(1&#x2212;&#x3b2;)ZrO, &#x3b2; AlO} (wherein x, y and z are weight percentages; x+y+z=100, 55&#x2266;x&#x2266;75, 10&#x2266;y&#x2266;35, and 5&#x2266;z&#x2266;30, &#x3b1; and &#x3b2; are moles; 0.4&#x2266;&#x3b1;&#x2266;0.8, and 0.01&#x2266;&#x3b2;&#x2266;0.07) and 2 to 10 parts by weight of a Zn&#x2014;B-silicate glass composition, per 100 parts by weight of the major composition. The multilayer ceramic chip capacitor and a multilayer ceramic circuit board for the electronic device comprise a plurality of dielectric ceramic layers, internal electrodes arrayed inside the dielectric ceramic layers, and outer electrodes electrically connected to the internal electrodes, characterized in that the dielectric ceramic layer is a sintered body of the dielectric ceramic composition mentioned above, and the internal electrode is made of a conductive base metal material.
