PURPOSE: A transformer including a heat sink is provided to effectively cool the transformer by forming a water cooling path which is bent a plurality of times in the heat sink. CONSTITUTION: A toroidal part(100) includes a toroidal core and a conductive coil(120). A toroidal insertion unit(200) surrounds the center part and the outer part of the toroidal core. The toroidal insertion unit includes a plurality of conductive members(210) and an insulating member(220). A heat sink(300) is installed on one end or both ends of the toroidal insertion unit. An insulating paper(400) is inserted into the heat sink and the toroidal insertion unit.
