The invention discloses a mouse cage type magnetostrictive longitudinal mode guided wave detection sensor. The two ends of each iron cobalt alloy thin strip are embedded into a groove of a toothed rubber layer; and end pressing buckles fix the toothed rubber layer and the plurality of iron cobalt alloy thin strips. The middle section of each iron cobalt alloy thin strip is spin-coated with a curedepoxy resin layer and is used for being in contact with the surface of a measured micro-tube. Two permanent magnetic rings are formed by splicing C-shaped permanent magnets, the two permanent magnetic rings are arranged at the two ends of an iron cobalt alloy cylindrical shell cage in a magnetic pole dissimilar mode and maintain coaxial with the iron cobalt alloy cylindrical shell cage, and the iron cobalt alloy thin strips are subjected to same-direction bias magnetization. A flexible coil is wound at the middle section of the iron cobalt alloy cylindrical shell, and electrical connection isconducted by a coil adapt
