The present invention relates to a laminated electronic component including internal electrodes formed by using a printing plate.

Description of the Related Art Conventionally, in the case of forming an internal electrode of a laminated electronic component by gravure printing, a solid recess corresponding to the shape of the formed internal electrode is formed, and the recess is filled with a conductive paste. It was transferred to the surface of the ceramic sheet. However, since the shape of the recess is large, due to the error in the filled conductive paste, the error in the size of the recess, and the process conditions,
There has been a problem that the shape of the transferred conductive paste does not match the shape of the preset internal electrode.

る。Here, when the small recesses are formed so as to be parallel to the end sides of the gravure printing plate, there are ridges that separate the recesses parallel and perpendicular to the printing direction. When printing is performed using a plate, there are portions along the ridge where the conductive paste is not printed. The non-printed portions formed by the ridges in the vertical direction are eliminated by the familiarity of the conductive paste, but the non-printed portions of the conductive paste by the ridges in the parallel method are not easily eliminated. Therefore, when the conductive paste pattern thus formed is dried to form the internal electrodes, the film thickness becomes non-uniform and, in some cases, a non-conducting portion may be formed in the internal electrodes, resulting in disconnection.
【０００７】一方で、端辺に一定の角度をもって形成し
