Abstract
A filter device includes a port, a reference potential part, at least one filter, a signal line, a first inductor, and at least one second inductor. A signal is input through the port, and/or a signal is output through the port. The reference potential part is placed at a reference potential. The at least one filter filters a signal. The signal line connects the port to the at least one filter. The first inductor is at least part of the signal line. The second inductor forms a connection between the signal line and the reference potential part. The first inductor and the at least one second inductor are inductively coupled to each other.
