PROBLEM TO BE SOLVED: To obtain a thin laminated dielectric filter with a microstrip structure which prevents deterioration in VSWR. SOLUTION: The microstrip line type laminated dielectric filter 10 includes: a ground electrode 11, a first line 14A as a resonator, and a second line 14B having a symmetric shape with respect to the first line 14A, which are formed in a laminated body 20 composed of laminated dielectric layers. A marking 15 made of a conductive film is formed on a top face on the side of the first line 14A of the laminated body 20. A wide section 16A is formed at a part overlapping on the marking 15 is formed in the first line 14A, while a wide section 16B is formed in the second line 14B in almost the same shape as the first line 14.
