PROBLEM TO BE SOLVED: To surely and easily fix stacked strip magnetic plates for the stacked magnetic core which has strip magnetic plates which differ in width, stacked along the thickness so that the width increases or decreases sequentially. SOLUTION: A fixing force operates on the magnetic plates 5', 5', etc., bundled by a protective tube 10' over nearly the entire length and specific flexibility is given, without generating machining strains, and then tolerance t an impact, vibration thermal shrinkage, etc., is obtained and a decrease in iron loss efficiency is reduced to suppress the variations and deterioration in magnetic characteristics. The surface is covered with the protective tube 10', which is effective in anticorrosiveness, damage prevention, etc.; and the protection tube 10' is colored as desired or given a desired display for facilitating identifying and distinguishing kind the standards, usages, manufactures, etc.
