Abstract

　スイッチ素子（６３）は第３配線パターン（６５）の導通を確立する。磁気抵抗効果膜（５３）は短絡する。したがって、例えば静電気放電に基づき過電流が発生しても、過電流は例えば第１配線パターン（６１）から第３配線パターン（６５）を経由して第２配線パターン（６２）に流通する。磁気抵抗効果膜（５３）に過電流の流通は最大限に抑制される。しかも、スイッチ素子（６３）や第３配線パターン（６５）は非磁性膜に埋め込まれる。スイッチ素子（６３）や第３配線パターン（６５）は磁気抵抗効果膜（５３）にできる限り近づくことができる。加えて、スイッチ素子（６３）や第３配線パターン（６５）は磁気抵抗効果膜（５３）の形成と同時に形成される。磁気抵抗効果膜（５３）の形成時にすでに磁気抵抗効果膜（５３）は短絡する。磁気抵抗効果膜（５３）の破壊はより確実に防止される。
