PROBLEM TO BE SOLVED: To provide a laminated array component wherein variation in electric characteristics between coils due to the presence of a metal-made direction recognition mark is suppressed. SOLUTION: In this L/C complex array component 1 which is a sintered laminate of rectangular ceramic sheets 2-12 made of a ceramic dielectric material or a ceramic magnetic material, first to fourth L/C parts are arranged with proper gaps in between them. Neighboring L/C parts are arranged in parallel in the direction squarely crossing the direction of the lamination of the ceramic sheets 2-12, and a direction recognition mark 32 is formed at a location near the inner of the long sides of the upper surface of the ceramic sheet 2. The ratio of the long side length to the short side length of the direction recognition mark 32 is set to be not lower than 5:1 so that the direction recognition mark 32 uniformly laps over each of the helical coils L1-L4 in the plan view.
