A process for producing a multilayered ceramic substrate having a step portion of a desired shape does not require complicated process steps and equipment. An auxiliary-layer-lined unfired ceramic body, which has a step portion in a principal surface thereof, has an unfired ceramic body and an auxiliary layer which is adhered to one principal surface of the unfired ceramic body and which is made of a material that is substantially unsinterable at a temperature at which the unfired ceramic body is fired. The auxiliary-layer-lined unfired ceramic body is fired at a temperature at which the unfired ceramic body is sinterable but the auxiliary layer is substantially unsinterable, while the auxiliary layer remains adhered to the unfired ceramic body. A pressing operation is performed by using a die having a projection placed on the side of the auxiliary-layer-lined unfired ceramic body retaining the auxiliary layer, so that the step portion, having a shape corresponding to the outer shape of the die projection, is formed in the side of the auxiliary-layer-lined unfired ceramic body retaining the auxiliary layer. |

A method of fabricating a ceramic stack structure having dielectric layers which are not easily cracked or delaminated is disclosed. In fabricating a ceramic stack structure having a plurality of dielectric layers and a plurality of internal electrode layers stacked alternately with each other, a carrier film (20) is prepared and a plurality of internal electrode print portions (21) are formed. A large print portion (225) is formed in such a manner as to cover the internal electrode print portions (21). The large print portion (225) is dried and a coat layer (23) is formed in such a manner as to smooth out the unevenness of the surface of the large print portion (225). The large print portion (225) is removed from the carrier film (20) and punched to produce an unsintered unit. The unsintered unit is punched while at the same time stacking and attaching the particular unsintered unit on another unsintered unit under pressure. This process is repeated to produce an unsintered stack body including a plurality of the unsintered units. The unsintered stack body is sintered into a ceramic stack structure. |
