    摘要： A photo-resist 11 of a dry film 10 is patterned to form opening portions 111 and non-opening portions 112 (see FIG. 1(a)). An electrically conductive paste 21 is applied by a doctor blade 31 (see FIG. 1(b)) and thereafter is dried (see FIG. 1(c)). Then, a release film 12 of the dry film 10 is removed (see FIG. 1(d)) and thereafter the dry film 10 is adhered to a ceramic green sheet 41 (see FIG. 1(e)). The photo-resist 11 is removed from the ceramic green sheet 41 to form an electrically conductive film 42 on the ceramic green sheet 41 (see FIG. 1(e)). The ceramic electronic component is manufactured by sintering the ceramic green sheet 41 having the electrically conductive film 41 formed.

    摘要： In the multilayer inductor, the substrate thereof is composed of a constituent belonging to spinel ferrite, and is furnished with internal conductors of a main constituent being silver at the interior of the substrate. The internal conductors are drawn outside of the substrate, and the drawn portions are provided with external electrodes. The internal conductors contain manganese and bismuth, and the manganese and bismuth contents at an interface between the internal conductors and the substrate are more than those of other ranges. MnO2 of 0.02 to 0.1 wt % and Bi2O3 of 0.5 to 1.2 wt % are added to a paste of the main constituent being silver to be used to the internal conductors, and the paste is baked together with spinel ferrite material.
