Original Abstract Submitted

A filter device includes a dielectric including a main surface, and a filter in the dielectric. The filter includes first and second inductors inside the dielectric. The first inductor includes a first coil with a winding axis corresponding to a normal direction to the main surface of the dielectric. The second inductor includes a second coil including flat-plate electrodes in the dielectric and extending linearly, and vias connected to the flat-plate electrodes and extending in a normal direction of the dielectric. In a plan view seen from the normal direction of the dielectric, an imaginary line does not intersect with an inner surface of the first coil, the imaginary line being drawn from a center position in an extending direction of the flat-plate electrodes in the second inductor to extend in a direction orthogonal or substantially orthogonal to the extending direction.
