An apparatus having a transformer for preventing loss of eddy current is provided to improve the efficiency of energy by preventing loss of eddy current using a metal pattern layer for preventing excursive magnetic flux and leaky magnetic flux. A transformer(112) is mounted on a PCB(Printed Circuit Board) substrate(111). A metal pattern layer(130) is formed on a rear surface of the PCB substrate corresponding to the transformer, wherein the metal pattern layer prevents the generation of excursive magnetic flux and leaky magnetic flux. The metal pattern layer is capable of being a copper pattern layer. A ferromagnetic structure(120) is installed below the PCB substrate. |
