Abstract:
An electronic circuit board includes a TMR element having two terminals connected to a power supply and a ground, respectively, at least through a lead. After a breakdown of a tunnel barrier film of the TMR element, at least a part of the lead breaks by an overcurrent due to a short circuit between the two terminals.
