The composition useful as a laminated ceramic condenser, contained 97.04-97.80 wt.% of BaTiO3, 1.42-1.92 wt.% of Nb2O5, 0.04-0.06 wt.% of MnO2, 0.33-0.45 wt.% of CaO, 0.31-0.41 wt.% of C2O2 and 0.10-0.12 wt.% of ZnO. Thus, the composition was mixed and crushed by ball-mill in Nylonjar for 1 hr, dried at 100 degree C, and added 97.80wt% of BaTiO3 for 1 hr. The composition was calcinated at 1,310 degree C for 2hrs and added 5 wt.% of polyvinyl acetate. Obtained product was molded at 1 ton/cm2 pressure in 10 mm of diameter and 15 mm of width. Thereafter baked at 1,310 degree C for 2 hrs, and coated Ag electrode in the both sides of the sintered body.
