The invention relates to the technical field of sensors, in particular to a strain sensor, a preparation method thereof and a fiber metal laminated board. The strain sensor comprises a substrate, a thin-film resistor and an electrode assembly, and the thin-film resistor and the electrode assembly are located on the substrate and electrically connected; the thin-film resistor is made of a nickel-carbon thin film, and the percentage of nickel atoms in the nickel-carbon thin film is 0.1-0.8. The strain sensor can detect the strain state of the internal structure of the fiber metal laminated board on line in real time in the using process. 本发明涉及传感器技术领域，具体而言，涉及一种应变传感器及其制备方法、纤维金属层压板。应变传感器包括基底、薄膜电阻和电极组件，其中薄膜电阻和电极组件位于基底上，薄膜电阻和电极组件电连接；薄膜电阻的材质为镍碳薄膜，镍碳薄膜中镍原子百分比为0.1～0.8。上述应变传感器能够实时在线检测纤维金属层压板使用过程中内部结构应变状态。
