PROBLEM TO BE SOLVED: To miniaturize a laminated composite device, which is constituted by stacking a plurality of circuit element boards, by shorter making the pattern length of inductor patterns, which are respectively formed on the circuit element boards, than that of conventional inductor patterns. SOLUTION: In a laminated composite device, at least one inductor pattern 20 is formed on each of a plurality of circuit element boards 1, the inductor patterns 20 are respectively arranged on the circuit element boards 1 formed with the inductor patterns 20 so that the magnetic center points 21 of the inductor patterns 20 on the circuit element boards 1 are aligned on the same axle and these patterns 20 are regulated the direction of current supply so that the directions of magnetic fields, which are formed by the current supply, become the same direction.
