(57) [Problem] To provide a capacitor in a multilayer circuit board itself using a photosensitive high dielectric composition. SOLUTION: The multilayer circuit board with a built-in capacitor according to the present invention comprises a substrate 1, a first conductor pattern 2 formed on the surface of the substrate 1, and the substrate 1 so as to cover the first conductor pattern 2. And at least a second conductive pattern 4 formed on the surface of the insulating film 3. The first conductive pattern 2 and the second conductive pattern 4 are Via hole 3 formed in insulating film 3 are electrically connected via a. The insulating film 3 is It is a high dielectric film which contains a polyimide resin or a polyamide imide resin, an acrylic polymer and a dielectric powder in a coexisting manner, and is patterned by a photo process, wherein the first conductive pattern 2 and the second conductive pattern 4 At least one pair of electrodes 2a, 2b constitutes a capacitor. |
