PURPOSE:To obtain smooth cut edges of a green sheet having interconnection patterns, even if they are along snap lines, by providing dummy patterns opposite the snap lines on the surface of the green sheet. CONSTITUTION:Green sheets 20 have wiring patterns 2 on their surfaces, and dummy patterns 22 are formed opposite the wiring patterns across snap lines on one or both of the green sheets. Accordingly, there is a smaller difference in thickness between the areas of the wiring patterns and the areas opposite the wiring patterns across snap lines on the green sheets. When the green sheets are sintered, the irregularities in internal density of the sintered laminate is minimized. As a result, the cut edges of the laminate become smooth if it is cut along snap lines. |
