<p>PROBLEM TO BE SOLVED: To reduce width and height in the external dimensions of a leakage transformer for multiple lights, used at a power supply circuit section so that it can be accommodated at a frame section around the display screen of a liquid crystal display, and to prevent magnetic leakage to the outside. SOLUTION: On one surface of a set of cores 2 and 8 for forming a closed magnetic circuit, a plurality of middle leg sections 3a and 3b, and inside groove sections 4a and 4b being concentric with each middle leg section are formed; and at the same time, an outside groove section 5 is formed so that each inside groove section is surrounded; a primary coil 10 is fitted to the outside groove section; and separate secondary coils 12a and 12b are fitted to each inside groove section.</p> |
