PROBLEM TO BE SOLVED: To provide a laminated filter element in which a plurality of dielectric layers can be laminated firmly and stably in manufacturing the laminated filter element. SOLUTION: The element has first spiral lines 31, 33 each having one end connected to a signal input electrode 1 and the other end connected to a signal output electrode 3, and second spiral lines provided each having one end connected to a grounding electrode 2 and the other end being opened and arranged in parallel to the first spiral lines 32, 34. The element is provided with a grounding pattern 35 connected to the electrode 2, and the ground pattern is formed in such a way that hollowed-out portions are disposed on a surface pattern.
