    摘要: A method for producing a capacitor includes the steps of: forming on a dielectric layer formed on a first electrode, an insulating composition, e.g., an organic polymeric compound containing a metal powder or an organometallic compound as a metal source, which is rendered conductive upon heating by radiation; and locally and gradually heating the insulating composition layer so as to form a second conductive electrode while measuring an increase in a capacitance between a conductor end portion for measuring a capacitance and the first electrode. According to this method, a capacitor having a precise capacitance can be formed.

    摘要: There is disclosed a wiring substrate comprising a wiring circuit pattern formed on a metal substrate with an insulating resinous layer interposed therebetween. In this wiring substrate, the insulating resinous layer is formed of a high molecular composition comprising thermosetting 1,2-polybutadiene containing 5 to 30% by weight of a high molecular softening agent such as hydrogenated polybutadiene. A method of manufacturing such a wiring substrate is also disclosed, wherein a light-reflecting pigment is included in the insulating resinous layer for the convenience of the subsequent laser trimming.
