WAVE DIVIDER AND COMMUNICATION DEVICE

PROBLEM TO BE SOLVED: To provide a wave divider and a communication device which can be downsized with an isolation characteristic maintained. SOLUTION: An antenna terminal 1 is provided. A receiving filter 4 connected to the antenna terminal 1 is provided. A transmitting filter 3 connected to the antenna terminal 1 in parallel with the receiving filter 4 and having a different passband center frequency from that of the receiving filter 4 is provided. An earth terminal 3c and an earth terminal 4c are made common by connecting a common inductance component 9 between the earth terminal 3c of the transmitting filter 3 and the earth terminal 4c of the receiving filter 4. Inductance components 3b and 4b which are other inductance components different from the common inductance component 9 are provided between the common inductance component 9 and a parallel resonator 3a' of the transmitting filter 3 and the common inductance component 9 and a parallel resonator 4a' of the receiving filter 4.
