PROBLEM TO BE SOLVED: To achieve an electronic component capable of improving isolation characteristics of a transmitting filter and a receiving filter. SOLUTION: A transmitting filter chip 3 is covered with a grounded metal part 5a, thereby grounding electromagnetic waves generated near the transmitting filter chip 3. Therefore, since any electromagnetic wave is not stagnant near the transmitting filter chip 3, Rx band isolation can be reduced. Furthermore, a receiving filter chip 2 and a matching circuit chip 4 are covered with a resin part 5b, thereby preventing electromagnetic waves generated near the transmitting filter chip 3 from being spread to a side of the receiving filter chip 2. Thus, Tx band isolation can be reduced. COPYRIGHT: (C)2010,JPO&INPIT
