PURPOSE:To obtain a one-turn cut type wound core consisting of a thin strip of amorphous magnetic alloy by abutting both end planes of laminar blocks after applying a smooth surface forming material to one of the end planes of each laminar block of square shape and opening the laminar blocks to incorporate a winding. CONSTITUTION:An amorphous magnetic alloy thin strip 1 is wound to form a wound body and thin wound body is cut and developed to form a plurality of groups of laminar blocks 7a-7c composed of a number of thin strips 1 laminated and having both end planes forming inclined planes. The blocks 7a-7c are laminated and are shaped into a square. A smooth surface forming material 21 is applied to one of the end plane of the shaped blocks 7a-7c. The blocks 7a-7c provided with the material 21 are opened and a winding 12 is incorporated. The both end planes of the developed blocks 7a-7c are abutted to form a wound core. Thus, a one-turn cut type wound core consisting of the thin strip 1 can be obtained.
