The invention belongs to the technical field of optical fiber application, and particularly relates to a refractive index type double-formant PCF-SPR probe filled with gold nanowires, and the refractive index type double-formant PCF-SPR probe filled with the gold nanowires is composed of a photonic crystal fiber and two gold nanowires; the two sides of the photonic crystal fiber are symmetrical tangent planes, groove openings which are symmetrically distributed are formed in the middles of the tangent planes, the two gold nanowires are located in the groove openings and used for external sensing, two sets of inner layer air holes which are symmetrically distributed are formed in the two sides of the groove openings, the number of the inner layer air holes in each set is four, and the number of the inner layer air holes in each set is four. Two groups of outer-layer air holes which are symmetrically distributed are formed in two sides of the inner-layer air holes, and the number of each group of outer-layer ai
