    Abstract: PROBLEM TO BE SOLVED: To restrain cracking of porcelain by lowering an internal stress between a conductor pattern and the porcelain when a conductive paste is coated direct on the porcelain and calcined to form a conductor pattern.
    SOLUTION: A conductive paste is composed of silver powder as a principal component and metal oxide powder of which primary particles have a hollow structure. The metal oxide is preferred to be silica, and preferably an electronic part is preferred to have a ceramic body and an internal electrode formed inside the ceramic part. The internal electrode is formed of the above-mentioned conductive paste. A surface electrode may be formed of the conductive paste.

    Abstract: PROBLEM TO BE SOLVED: To provide a printed circuit substrate material for an embedded passive element which has a good electromagnetic characteristic and reliability. SOLUTION: One printed circuit substrate material for an embedded passive element is composed of a copper foil, a resin binding layer which contains a resin of 70 vol%-100 vol%, a filler less than 30 vol%, and a functional layer which contains a resin and a filler, and another printed circuit substrate material is composed of a copper foil, a first resin binding layer which contains a resin more than 70 vol% to 100 vol% and a filler less than 30 vol%, a functional layer which contains a resin and filler, and a second resin binding layer which contains a resin of 70 vol%-100 vol% and a filler less than 30 vol%, and a copper foil. The characteristics of the functional layer of a dielectric characteristic, an electromagnetic characteristic, etc. do not deteriorate and an adhesive force between a copper conductive layer and the functional layer can be held by interposing the resin binding layer between the copper foil and the functional layer even if the content of filler of the functional layer increases.
