PROBLEM TO BE SOLVED: To provide a noise filter that can have characteristics stabilized and be made compact and low-cost, by removing the factors for the dispersion in the impedance characteristics, since a filter portion and a connector portion are integrated and a connection portion between a coil and a connector is made short or eliminated. SOLUTION: The noise filter has a bobbin case 3, housing a core 2 and a connector terminal 4 at the same time as at an air core section of the coil 1, wherein the coil 1 and connector terminal 4 are directly jointed to each other.
