PROBLEM TO BE SOLVED: To provide a lead frame that has a shape with high reliability of connection to a PWB(Printed Wiring Board) used for a mobile phone terminal or the like whose downsizing, weight reduction and high circuit integration are advanced, and to provide a SAW filter employing the frame. SOLUTION: Each of the lead frames 10 has an inner lead 1 and an outer lead 2, is placed in parallel, an interval A1 between the adjacent inner leads 1, an interval A2 between the adjacent outer leads 2, and also a width A3 of each inner lead 1, and a width A4 of each outer lead 2 can freely be selected so as to match with a wireless pattern or the like of the PWB. Furthermore, in the SAW filter 20, the lead frame 10 described above is fixed to a resin mold base 4, connected to a SAW chip 7 and a resin mold cap 5 covers the SAW filter 20. |
