PASSIVE ELECTRONIC PARTS, IC PARTS, AND WAFER

摘要

The present invention relates to a passive electronic part comprising a substrate 1 and a passive circuit 2. The substrate 1 is provided with an inorganic insulating layer 11 constituted of a composition achieved by mixing a ceramic constituent and a glass constituent. The passive circuit 2, which is normally constituted of a conductor pattern, is provided on one surface 111 of the inorganic insulating layer 11. It is desirable that the surface 111 of the inorganic insulating layer 11 where the passive circuit 2 is formed be polished. An electronic part with which the conductor pattern can be made finer and a design can be implemented based upon a small pattern area is provided.
