<p><P>PROBLEM TO BE SOLVED: To improve manufacturing work efficiency and to improve magnetic characteristics in an iron core for a transformer having thin plates of magnetic materials stacked. <P>SOLUTION: The transformer 1000<SB>A</SB>includes annular rectangular iron cores 1a and 1b formed by stacking a plurality of blocks comprising a plurality of strips of thin plates of magnetic materials and connecting respective length-directional tip parts and end parts of the plurality of blocks. Connection parts of the plurality of blocks are provided at long-side parts, and the connection parts are arranged at a position shifted in a length direction of the long-side parts between adjacent blocks, and the plurality of connection parts of all of the plurality of blocks are arranged dispersedly over a range longer than the length of linear parts of short-side parts of the iron cores in the long-side parts. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
