1. A noise filter connected to a wire of a wire harness that links a power source and a load, and eliminating noise transmitted from the power source to the load, comprising:
a housing that includes a flat cylindrical outer circumferential wall, a bottom that seals one end of the outer circumferential wall, and an opening that is formed on the end of the outer circumferential wall that is on the opposite side from the bottom;
a capacitor that is housed inside the outer circumferential wall;
a ground terminal that is connected to one electrode of the capacitor; and
a noise filter wire that electrically connects another electrode of the capacitor to the wire of the wire harness,
wherein the ground terminal includes a portion inside the housing that is positioned inside the outer circumferential wall and a portion outside the housing that includes a grounding portion configured so as to extend outside the housing through the opening and be grounded on a vehicle body panel,
the ground terminal is a plate member having a first surface and a second surface, and
the housing makes contact with the first surface of the ground terminal at the portion of the ground terminal inside the housing and makes contact with the second surface of the ground terminal at the portion of the ground terminal outside the housing.
