PURPOSE: A transformer is provided to prevent the crack and deformation of a core by containing aggregate in an adhesive member which connects the cores. CONSTITUTION: A transformer(10) includes a bobbin(100), a first and second core units(110,120), an adhesive member(130) and aggregates(140). The bobbin includes a body(101), a coil(103) wound on the outer surface of the body and a hollow(102) passing through the body. The bobbin is made of an insulating resin to insulate the coil and the first and second core units each other. The first core unit includes a first core(111) inserted into the hollow, a second core(112) arranged in both sides of the first core and a third core(113) connecting the first core and the second core.
