A filter capacitor (2) is provided with a pair of direct current terminals (first direct current terminals), which are configured of a positive electrode-side main terminal (12a) that receives a direct current voltage from a direct current power supply (1), and a negative electrode-side main terminal (12b), said filter capacitor having three capacitor elements (9a-9c), including a capacitor element (9a) positioned, in electrically connection mode, at an end portion on one side, and a capacitor element (9c) positioned at an end portion on the other side. The filter capacitor is configured such that a first conductor path length (W1) between the positive electrode-side terminal (14a) of the capacitor element (9a), and the positive electrode-side main terminal (12a), and a second conductor path length (W2) between the positive electrode-side terminal (16a) of the capacitor element (9c), and the positive electrode-side main terminal (12a) are substantially equal to each other, and a third conductor path length (W3) between the negative electrode-side terminal (14b) of the capacitor element (9a), and the negative electrode-side terminal (12b), and a fourth conductor path length (W4) between the negative electrode-side terminal (16b) of the capacitor element (9c), and the negative electrode-side main terminal (12b) are substantially equal to each other. |
