Abstract
A magnetostriction type stress detector including a passive member to which an external force is applied, which passive member is formed of a magnetic material; a magnetic shielding member provided around the passive member, which magnetic shielding member is formed with a plurality of slits; and a detection coil provided around the magnetic shielding member for detecting a change in magnetic permeability due to a stress in the passive member to be generated by the external force, through the slits of the magnetic shielding member.
