Claim 10:
11. A power module applied to an electric power conversion device in which a plurality of upper-lower arm circuits are connected to an electric power line in parallel, the power module comprising:
the plurality of upper-lower arm circuits;
a capacitor connected to each of the plurality of upper-lower arm circuits in parallel;
an upper wiring that connects an upper arm configuring each of the plurality of upper-lower arm circuits and a positive electrode terminal of the capacitor;
a lower wiring that connects a lower arm configuring each of the plurality of upper-lower arm circuits and a negative electrode of the capacitor;
an upper electric power wiring that is an electric power wiring connected to the electric power line and connects a high potential line of the electric power line and the upper wiring;
a lower electric power wiring that is an electric power wiring connected to the electric power line and connects a lower potential line of the electric power line and the lower wiring;
the upper-lower arm circuit includes a semiconductor device;
the power module further includes
a drive substrate configured to output a drive signal to the semiconductor device,
an output wiring connected to an output terminal of the semiconductor device,
a current sensor that is mounted on the drive substrate and is configured to detect a current flowing through the output wiring;

the output wiring extends in one direction, and includes
a detected portion at which the current is detected by the current sensor and
a bent portion that has a first end connected to the detected portion and extends in a different direction from the detection portion; and

the bent portion includes
a terminal portion that is placed on a second end opposite to the first end and is connected to a different member, and
a facing portion that extends from the terminal portion towards the detection portion and faces the different member together with the terminal portion.
