Problems to be Solved by the Invention In the above conventional structure, the insulating protective case 1. Due to the configuration using the coil bobbin 7 and the bottom plate 18, clearance between each component is required, making it difficult to reduce the height dimension, and the device cannot sufficiently meet the market's needs for lighter, thinner, shorter and smaller devices. In addition, the number of parts is large, resulting in high material costs and a complicated assembly method. Furthermore, since a transformer is generally a power component, the reduction in height due to the sunken structure has the disadvantage that the installation area of the transformer increases.
