PROBLEM TO BE SOLVED: To provide a dielectric laminated filter, capable of freely controlling an attenuation pole on the outside of a passing band. SOLUTION: In this filter constituted by electromagnetically coupling plural resonators with each other, a bypass circuit constituted of the serial circuit of bypass capacitors 207a and 207b and a transmission line 206 is provided parallelly to skip magnetic coupling 201a between non-adjacent resonators 103a and 103c. Thus, without being affected by the skip magnetic coupling between the non-adjacent resonators, the capacity of the bypass capacitor is adjusted, and the attenuation pole on the outside of the passing band is freely controlled.
