The invention belongs to the technical field of manufacturing for shielding an external geomagnetic field, and particularly relates to a cobalt-based amorphous composite material convenient to form. According to the composition of the cobalt-based amorphous composite material, a high-magnetic-conductivity cobalt-based amorphous substance is used as a functional layer for shielding the external magnetic field, and the upper surface and the lower surface of the functional layer are filled with polyimide for protecting the internal cobalt-based amorphoussubstance and facilitating forming. When the material is used, the material can form various magnetic shielding structures through stamping, so that the material can be directly used as a structural body, and an effect of shielding the external magnetic field is achieved. Compared with the prior art, the material has the characteristics of convenience in forming, light weight, certain low-frequency magnetic field shielding effect and the like. 本发明属于屏蔽外界地磁场的制造技术领域
