Claim 5:
6. The high-frequency front end module according to claim 5,
wherein, in a case where two-uplink and two-downlink in which simultaneous transmission in the first transmission band and the second transmission band is performed and in which simultaneous reception in the first reception band and the second reception band is performed, one of a first connection state in which the third terminal and the first terminal are conductive to each other and the fourth terminal and the second terminal are conductive to each other, and a second connection state in which the third terminal and the second terminal are conductive to each other and the fourth terminal and the first terminal are conductive to each other is selected,
wherein in a case of one-uplink two-downlink in which transmission in the first frequency band is performed and simultaneous reception in the first reception band and the second reception band is performed, one of a third connection state in which the third terminal and the first terminal are conductive to each other, and a fourth connection state in which the third terminal and the second terminal are conductive to each other is selected, and
wherein in a case of one-uplink two-downlink in which transmission in the second frequency band is performed and simultaneous reception in the first reception band and the second reception band is performed, one of a fifth connection state in which the fourth terminal and the first terminal are conductive to each other, and a sixth connection state in which the fourth terminal and the second terminal are conductive to each other is selected.
