PURPOSE: An inverter transformer is provided to emit heat generated in a primary coil efficiently while reducing material of a trans cap and costs. CONSTITUTION: An inverter transformer is composed of a first bobbin(10), a second bobbin(30), a trans cap(50), and a pair of u-type core(70). The first bobbin includes base portions(11a,11b) and a primary coil, and a pin of rotated-L shape is protruded to downward and side. The base is formed at the both sides of the length direction of the first bobbin, and the primary coil(14) is wound inside the base.
