A body 12 of a chip-type transformer includes two magnetic plates 14, 30 and insulating sheets 16, 20, 24, and 28. Ring-shaped patterned electrodes 18, 22 and 26 are formed on the insulating sheets 16, 20 and 24. The ends 18a and 18b of the patterned electrode 18 and the ends 26a and 26b of the patterned electrode 26 are led out to the same side of the insulating sheets 16 and 24. The ends 22a and 22b of the patterned electrode 22 are led out to the opposite side of the insulating sheets. The magnetic plates 14, 30 and the insulating sheets 16, 20, 24 and 28 are laminated, and external electrodes connected to the patterned electrodes are formed. The ends 18b and 26a of the patterned electrodes are connected by the external electrodes.

[ What is claimed is:] [1.] A method of manufacturing a chip transformer comprising the following steps:(a) preparing a first magnetic plate;(b) forming an insulating sheet on said first magnetic plate;(c) forming a first plurality of ring-shaped patterned electrodes on said insulating sheet;(d) forming a second insulating sheet on said patterned electrodes, and further forming a second plurality of ring-shaped patterned electrodes on said second insulating sheet so that said second plurality of patterned electrodes are positioned above said first plurality of patterned electrodes;wherein said first and second insulating sheets are formed by exposing and developing light-curable polyimide resin;wherein said first and second pluralities of ring-shaped patterned electrodes are formed with approximately equal line lengths, and with respective ones of said first and second pluralities overlapping each other with said second insulating sheet therebetween;(e) laminating a third insulating sheet and a second magnetic plate on said second plurality of patterned electrodes to make a laminate body;(f) cutting said laminate body to form a plurality of cut laminate bodies;(g) forming external electrodes connected to said first plurality and said second plurality of patterned electrodes on the external faces of each of said cut laminate bodies.
