PROBLEM TO BE SOLVED : To prevent the capacity temperature characteristics of a dielectric layer from being deteriorated due to the penetration of components from the other layer in a laminated electronic component equipped with a plurality of layers constituted of dissimilar materials.
SOLUTION : This laminated electronic component such as a multi-layered circuit substrate 1 is provided with base material layers 2, 4 and 6 containing glass materials, a functional material layer 3 containing ceramic materials having dielectric characteristics, and a functional material layer 5 containing magnetic substance ceramic materials. The base material layers 2, 4 and 6 are put in a sintered status, and the functional material layers 3 and 5 are put in a non-sintered status. Ceramic powders contained in the functional material layers 3 and 5 are fixed to each other when a portion of the materials of the base material layers 2, 4 and 6 are diffused or fluidized. The compound of rare earth elements and TiO2 is used as dielectric ceramic materials contained in the functional material layer 3.
