PROBLEM TO BE SOLVED: To provide a compact laminated filter in which a Q value can be further improved by forming inductance elements by through-holes. SOLUTION: Input and output terminal electrodes 3 and 4 are formed on the both edge faces of a laminated body 1. Ground electrodes 5 are formed on the both side faces of the laminated body 1. A pair of inductance elements constituted of through-hole electrodes 16 and 17 are formed in the laminated body. Ends of the inductance elements are electrically connected with the input and output terminal electrodes 3 and 4, and the other ends are connected with a shield electrodes 21 formed of a conductive layer. Capacitors connected with the inductance elements in parallel are formed in the laminated body 1. The rate W/d of a diameter (d) of the through-hole electrodes 16 and 17 to width W between the ground electrodes 5 and 5 on the both edge faces of the laminated body 1 is set 1.6 or more and 11.4 or less.
