The utility model discloses a linear optical fiber probe based on surface enhanced Raman scattering, which comprises an optical fiber, a fiber core is arranged inside the optical fiber, a cladding is coated outside the optical fiber, and one end of the optical fiber is of a linear structure with the upper top surface and the lower bottom surface being planes and the two side surfaces being arc surfaces. The fiber core is of a linear structure, the thickness between the upper top face and the lower bottom face of the linear structure is not smaller than the diameter of the fiber core, the radius of the arc face is equal to the outer diameter of the cladding, and metal nanoparticles are evenly distributed on the outer surface of the linear structure. The optical fiber SERS probe can be combined with a Raman spectrometer to form an optical fiber Raman sensing detection device, the practical process of the optical fiber SERS probe is promoted, a preparation method of the optical fiber probe with better sensitivit
