PROBLEM TO BE SOLVED: To provide a composite sheet simultaneously satisfying thinning of an insulating layer and the thickening of a wiring layer, while easily forming a fine wiring, and to provide a manufacturing method for a laminated part. SOLUTION: A photoresist layer 13 is formed on the surface of a carrier film 10 through which a light can be transmitted, and recessed-shaped patterns 13b are formed to the photoresist layer 13 by exposure and development. The patterns 13b are filled with light-nontransparent conductor paste, and the photoresist layers 13a are removed. The upper section of the carrier film 10 with a wiring layer 3a formed thereto is coated with a light-curable insulator paste, containing a ceramic material at a thickness larger than the thickness of the wiring layer 3. Only a light-curable ceramic-layer forming section is cured by irradiating the rear of the film 10 with light, and the light uncured section of the light-curable ceramic layer is dissolved and removed, thus manufacturing the composite sheet composed of the light-curable ceramic-layer wiring layer 3a.
