Abstract

An LC composite component comprises a laminated structure which is formed by stacking first and second inductor layers while holding a capacitor layer between the same. The first and second inductor layers comprise magnetic members and conductor lines formed inside the magnetic members respectively. The capacitor layer comprises a dielectric member and first and second internal electrodes which are provided within the dielectric member to be opposite to each other. First and second external electrodes are provided on first and second opposite end surfaces of the laminated structure, while a third external electrode is formed on at least one of first and second opposite side surfaces. First ends of the conductor lines provided in the first and second inductor layers are connected to the first and second external electrodes respectively, while second ends of the conductor lines are electrically connected with each other through the second internal electrode provided in the capacitor layer. The first internal electrode provided in the capacitor layer is electrically connected with the third external electrode. Thus, obtained is an LC composite component which has two inductors interpo…
