Patent ID: 7502213

Claim:
A surge absorber comprising: a first terminal electrode; a second terminal electrode; a third terminal electrode; an inductor portion having a first internal conductor and a second internal conductor mutually coupled in a polarity-reversed relation, wherein one end of the first internal conductor is connected to the first terminal electrode, one end of the second internal conductor is connected to the second terminal electrode, and an other end of the first internal conductor is connected to an other end of the second internal conductor, the coupling between the first and second internal conductors being positive and not negative; a surge absorbing portion having a first internal electrode connected to a connection point between the first internal conductor and the second internal conductor, and a second internal electrode connected to the third terminal electrode; and a capacitor portion having a capacitance component connected between the first terminal electrode and the second terminal electrode, wherein the inductor portion is comprised of a lamination of a first inductor layer on which the first internal conductor is formed, and a second inductor layer on which the second internal conductor is formed, the surge absorbing portion is comprised of a lamination of a first varistor layer on which the first internal electrode is formed, and a second varistor layer on which the second internal electrode is formed, each of the first and second varistor layers contains ZnO as a principal component and contains at least one element selected from the group consisting of rare earths and Bi, and Co as additives, each of the first and second inductor layers contains ZnO as a principal component and contains rare earths as additives, and substantially does not contain Co, and a content of the additives in the first and second inductor layers is not less than 0.02 mol % or more than 2 mol %, based on a total amount of ZnO in the first and second inductor layers.
