The invention provides a gap-butt amorphous core with noise reduction function of glue coating. The gap-butt amorphous core is formed by packing a plurality of amorphous core plates; the amorphous core plates are divided into a plurality of core plate groups; the two ends of one core plate are butted at the bonding land of the core, a micro seam with equivalent width inside and outside is formed in the middle of the core plate, and the micro seams of any core plate group have a distance with the micro seams of the adjacent core plate group along the tangential direction of the amorphous core; the glue coating is coated at least on part of the area of the front end surface and the back end surface of the amorphous core. The gap-butt amorphous core of the invention can effectively prevent the magnetic resistance at the bonding position from being increased greatly and is beneficial to enhancing the intensity of the core, reducing the noise, ensuring the transmission of magnetic flux and improving the property o
