VOLTAGE CONVERTER

PROBLEM TO BE SOLVED: To provide a voltage converter which deals with multiple primary and secondary coils having different wire diameters.SOLUTION: Each terminal connection part 4 include: a terminal holding part 41 holding a primary side terminal 111, 112 or a secondary side terminal 121, 122; a fixing part 43 fixing the terminal holding part 41 to a third flange part 322; and a conduction part 42 connecting with the primary side terminal 111, 112 or the secondary side terminal 121, 122 through the terminal holding part 41 and establishing electrical continuity with the exterior thereof. This structure allows the fixing part 43 fixing the terminal connection part 4 to the third flange 322 and the terminal holding part 41 holding the primary side terminal 111, 112 or the secondary side terminal 121, 122 to be disposed in different positions.
