Filter and front end circuit

A filter comprising:

• an input terminal;
• an output terminal;
• a ground terminal;
• a first parallel resonant circuit including a first capacitor and a first line, each of the first capacitor and the first line being shunt-connected to a first node of a series pathway connecting the input terminal and the output terminal;
• a second parallel resonant circuit including a second capacitor and a second line, each of the second capacitor and the second line being shunt-connected to a second node of the series pathway, the second node being different from the first node;
• a first dielectric layer having a surface on which a first connection line is disposed;
• and
• a second dielectric layer having a surface on which the first line and the second line are disposed, the second dielectric layer being arranged on or above the first dielectric layer and having first, second, third, fourth, fifth, and sixth via wirings that are penetrating through the second dielectric layer, the first via wiring electrically connecting the first line to the series pathway, the second via wiring electrically connecting the first line to the ground terminal, the third via wiring connecting the first line at a position between the first via wiring and the second via wiring to the first connection line at a first position of the first connection line, the fourth via wiring electrically connecting the second line to the series pathway, the fifth via wiring electrically connecting the second line to the ground terminal, the sixth via wiring connecting the second line at a position between the fourth via wiring and the fifth via wiring to the first connection line at a second position of the first connection line different from the first position of the first connection line.
