A composite electronic component that includes an insulation substrate having a principal surface; a thin-film capacitor on the principal surface of the insulation substrate; a laminated insulation protection layer covering the thin-film capacitor; a first extended wiring in the insulation protection layer and connected to the thin-film capacitor; a first resin layer on the insulation protection layer, first and second thin-film resistors in the first resin layer; a through-hole penetrating the first resin layer in a thickness direction thereof so as to expose the first extended wiring; a first rewiring in the first resin layer and connected to the first extended wiring through the through-hole; and a second resin layer on the first resin layer. The interior of the through-hole is filled with the second resin layer, and the through-hole does not overlap the thin-film capacitor.

Composite electronic component

A ferroelectric thin film element 1 constructed by forming a MgO thin film 3 oriented in the direction (100), a lower electrode 4 composed of an alloy thin film of a Ni--Cr--Al system oriented in the direction (100), a ferroelectric thin film 5 composed of a PbTiO.sub.3 thin film oriented in the direction (111), and an upper electrode 6 in this order on a substrate composed of (100) silicon 2.
