ABSTRACT:
A ceramic electronic element having improved the continuity of inner electrode layers while suppressing the decrease in adhesion between its dielectric layers and inner electrode layers and the deterioration in functions of the inner electrode layers, and a method of making the same are provided. In the method of making a ceramic capacitor (10) in accordance with the present invention, an electrode paste (22) is applied to a surface (20a) of a green sheet (20) and fired, so as to form a dielectric layer (12) laminated with an electrode layer (14). Since the electrode paste (22) is doped with a BaTiO3powder, the adhesion between the dielectric layer (22) and inner electrode layer (14) after firing is significantly restrained from lowering, and the sintering start temperature of the electrode paste (22) is close to that of the green sheet (20). Since the electrode paste (22) is doped with a metal resinate, functions of the inner electrode layer (14) are significantly restrained from deteriorating when the insulating BaTiO3powder is added to the electrode paste (22), and the sintering start temperature of the electrode paste (22) approaches that of the green sheet (20).
