Abstract

PURPOSE:To reduce the cost of manufacture by mounting an elastic surface wave element on a printed board by face down bonding as a filter element used for the VHF and UHF bands and then by dipping in a resin solution and covering it with resin. CONSTITUTION:The surface of an elastic surface wave element 13 is coated with a sound absorbing material 14 except at a pad 15 and a surface wave propagation path part 16. On a printed board 17, a pad 18 for electrode connection, a pattern 19 for connection, etc., are formed, and terminals 20 are connected. The formed element 13 and printed board 17 are faced mutually with the surfaces counter to each other, and on the pad 15 of the element 13, a conductive material 21 such as a solder ball is placed in contact with the pad 18 of the printed board 17. Then, the element 13 and printed board 17 are joined together by heating or pressing. Those joined element 13 and printed board 17 are dipped in a solution of resin to form a resin coating over the external surface.
