The invention relates to a minitype electromagnetic broadband vibration energy collector, which belongs to the technical field of micro electromechanical systems. The minitype electromagnetic broadband vibration energy collector comprises an insulating substrate, a planar spiral induction coil, a vibration pick-up structure and a support structure, wherein the insulating substrate, the planar spiral induction coil and the vibration pick-up structure are orderly arranged from the right lower part to the upper part; and the support structure is positioned on the outer side of the planar spiral induction coil and the vibration pick-up structure and fixedly connected with the insulating substrate. The invention collects broadband energy by superposing vibration modes of a plurality of circular permanent magnets connected by springs, and realizes integrated manufacturing of permanent magnets by a microstructure graphical method. Since the graphical permanent magnet can have a thick microstructure, the graphical pe
