Abstract:
1. A conductive paste composition for inner electrodes, comprising: a metal powder having a particle size ranging from 50 nm to 300 nm; and a binder resin, the binder resin including a high-molecular-weight polyvinylbutyral resin having a molecular weight of 250 thousand to 400 thousand, a low-molecular-weight polyvinylbutyral resin having a molecular weight of 50 thousand to 150 thousand, and a rosin ester, wherein in the conductive paste composition, the weight ratio of the binder resin to the metal powder is between 0.04 and 0.10, and in the binder resin, the weight ratio of the low-molecular-weight polyvinylbutyral resin to the high-molecular-weight polyvinylbutyral resin is between 0.5 and 1.5.
