Multilayered filter device

A multilayered filter device comprising:

• a first terminal;
• a second terminal;
• a plurality of resonators arranged between the first terminal and the second terminal in a circuit configuration;
• and
• a stack for integrating the first terminal, the second terminal, and the plurality of resonators, the stack including a plurality of dielectric layers stacked together, wherein
• the plurality of resonators include:
• at least one parallel resonator having one end not connected to a ground, and another end connected to a path connecting the first terminal and the second terminal without being routed through the ground, and
• at least one serial resonator, only one end of which is connected to the path, and another end of which is connected to the ground,
• the at least one serial resonator includes a first conductor layer wound around an axis extending in a direction parallel to a stacking direction of the plurality of dielectric layers,
• the at least one parallel resonator includes a conductor structure wound around an axis extending in a direction orthogonal to the stacking direction of the plurality of dielectric layers, the conductor structure includes two through hole lines and a second conductor layer electrically connected to one end of each of the two through hole lines, and each of the two through hole lines is constituted by a plurality of through holes being connected in series,
• the stack includes a first surface located at a first end in the stacking direction and a second surface located at a second end in the stacking direction and four side surfaces connecting the first surface and the second surface, and
• the first conductor layer includes three portions each located between a corresponding one of three side surfaces of the four side surfaces and at least part of the conductor structure when seen in the stacking direction.
