Claim:
1. A thin film element, comprising: an electrode layer disposed on a substrate; a protection layer formed to cover the electrode layer; a first opening extending though the protection layer; a second opening extending through the protection layer; a first interconnect layer having a first portion disposed on the protection layer and a second portion disposed along the first opening; a second interconnect layer having a first portion disposed on the protection layer and a second portion formed along the second opening; a pair of external electrodes electrically coupled to the first and second interconnect layers, respectively; first surface metal layers disposed on the respective second portions of each of the first and second interconnect layers; and second surface metal layers disposed on the respective first portions of the first and second interconnect layers, wherein the pair of external electrodes is in direct contact with the first and second interconnect layers, wherein the second surface metal layers extend in a same plane with the first surface metal layers, wherein a material of the first surface metal layers is Ni, and wherein the second surface metal layers are films formed by a vacuum thin film method.
