1. 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; and
an output wiring that connects at least one of a plurality of main terminals of the upper arm and at least one of a plurality of terminals of the lower arm,
wherein:
the output wiring includes a facing portion that faces each of the upper wiring and the lower wiring,
the facing portion includes a first facing portion that faces the upper wiring and a second facing portion that faces the lower wiring, and
in the output wiring, a position of the first facing portion is different from a position of the second facing portion.
