PROBLEM TO BE SOLVED: To provide a filter capable of improving the shoulder characteristics of the filter, and to provide a method for adjusting frequency in which center frequency is maintained, while the bandwidth is widened and an attenuation value can be increased. SOLUTION: In the laminated dielectric filter, the width of a turnup electrode 30c in a stripline 3a in two striplines 3a and 3b is widened and formed on the turnup electrode 30c side of the stripline 3b from the main strip line 30a of the stripline 3a.
