    Abstract: An object is to improve a core and heat radiation properties from the coil, and to reduce the size of a transformer. In order to attain the object described above, a transformer includes a bobbin wound around with a coil, a columnar core center portion in which the bobbin is mounted, and a plurality of core leg portions joining both ends of the core center portion on the outside of the coil. The size of the core leg portion is larger than the size of the other core leg portions, and the core leg portion includes a flat outer circumferential surface approximately parallel to a surface which is tangent to an outer circumferential side surface of the coil. The transformer is disposed in a housing such that the outer circumferential surface of the core leg portion is tangent to a floor surface of the housing.
