Claim 2:
3. The DC-DC converter according to claim 1, wherein
the second coil has one end connected to a terminal of the first coil, the terminal of the first coil being closer to the first output terminal,
the diode is provided between the second intermediate terminal and a terminal of the second coil, the first coil being not connected to the terminal of the second coil, such that a direction from the second intermediate terminal to the second coil is a forward direction, and
the first coil and the second coil are magnetically coupled such that a current is made flow through the second coil in a direction from the diode to the first output terminal by mutual induction as the current flowing through the first coil in the direction from the first intermediate terminal to the first output terminal increases.
