PROBLEM TO BE SOLVED: To provide a low-cost compact LC-type filter module which is simple to manufacture and easy to assemble, and has a proper filtering qualities. SOLUTION: Capacitors 2, 2' are composed of first slender elements 4, 4' made of a conductive material. The first elements are partly fitted into holes 5, formed in a second element 6 made of a conductive material. The second element is electrically connected to second elements of one or a plurality of capacitors, or to a second element common to various capacitors 2, 2', as required. An inductive material 7 covers at least the inner walls, defining the holes 5, edges 5' of openings of the holes or bores 5, and at least a plurality of outer surface portions, preferably the entire outer surface of one or a plurality of second elements 6 adjacent to the edges 5'.
