An interposer (300, 400, 500, 600, 700, 800, 900, 1000, 1100, 1200) having an integrated magnetic device. A magnetic device is disposed on a substrate (301, 401, 501, 601, 701, 801); a coil of the magnetic device is formed by connecting metal wires (311, 321, 411, 421, 511, 521, 611, 621, 711, 721, 811, 821, 911, 921, 940, 950, 1011, 1021, 1040, 1050) that are disposed in the substrate (301, 401,501, 601, 701, 801). The resistance of the magnetic device is remarkably reduced, the inductance density and quality factor of the integrated magnetic device are improved, the volume of the magnetic device is reduced, and thus the efficiency is improved without affecting the surface flatness of the interposer or occupying the existing metal interconnecting wires. The performance of the integratedmagnetic device is improved and the integration of high-performance magnetic devices is implemented on the premise of ensuring the interconnection function of the silicon interposer against impairment. 种具有集成磁性器件的转接板(300，400，50
