Abstract:
A method for manufacturing a printed wiring board includes forming an uncalcined layer containing a raw ceramic material on a first metal layer, firing the uncalcined layer formed on the first metal layer such that a high dielectric constant layer having a ceramic body calcined in a sheet form is formed on the first metal layer, forming a second metal layer on the high dielectric constant layer on the opposite side of the high dielectric constant layer with respect to the first metal layer such that a layered capacitor having the high dielectric constant layer and first and second layer electrodes sandwiching the high dielectric constant layer is formed, and disposing the layered capacitor in a main body.
