<p>PROBLEM TO BE SOLVED: To provide a transformer in which lead wires can be drawn out of a coil without welding nor notching the wire members at the end sections of copper or aluminum sheets by making the widths of the copper or aluminum sheets narrower than the linear width of a coil lead-out section and which has high insulation reliability. SOLUTION: In the transformer provided with a coil using a plurality of copper or aluminum sheets 2 and 3 in the widthwise direction of the sheets 2 and 3, the widths of the sheets 2 and 3 are made narrower than the linear width of the coil lead-out section 11. The lead wires 21 and 31 are drawn out of the coil 1 without connecting the lead wire members to the winding starting and end sections of the sheets 2 and 3.</p> |
