PURPOSE: To provide a laminated filter used for a communication equipment or the like in which the attenuation amount on the high pass side can be taken large.
CONSTITUTION: A capacitor capacity 7a and L components 4a and 4b are connected between an input electrode 13A and a ground, and a capacitor capacity 8a and an L component 14a are serially connected between the capacitor capacity 7a and the ground, and between the L components 4a and 4b and the ground. Then, a capacitor capacity 7b and L components 4c and 4d are connected between an output electrode 13B and the ground, and a capacitor capacity 8b and an L component 14b are serially connected between the capacitor capacity 7b and the ground, and between the L components 4c and 4d and the ground. Then, the large attenuating amount can be obtained even at the high pass side by the serial oscillation due to the capacity 8a and the L component 14a, and the serial oscillation due to the capacity 8b and the L component 14b.
