PROBLEM TO BE SOLVED: To suppress an increase in the number of components to be used and the number of connection points, and to sufficiently reduce high frequency noise over a wide frequency bandwidth. SOLUTION: The capacitor type high frequency noise filter for an on-vehicle device comprising at least one capacitor having one grounded end, is equipped with: a conductive electric wire 11 for connecting between an input terminal 14 and an output terminal 15, and a capacitor, having one end connected to a portion of the electric wire 11, and the grounded other end. An inputting part (one section 11a of an input side) being one section of the input terminal side of a line, and an outputting part (one section 11b of an output side) being one section of the output terminal side, intersect in a position where they are adjacent to each other, and form at least one loop 16 between the inputting part and the outputting part; one end of the capacitor is connected to a place on the way to the loop 16; and an inductance of the loop 16 and the capacitor constitute a filter.
