A magneto impedance sensor element with electromagnetic coil comprised of:
a terminal board on which an extended groove which extends in one
direction has been formed; an electromagnetic coil, made with one part of
the coil formed in a spiral shape inside the extended groove in the
terminal board, and joined to each tip of that coil the other part of the
coil placed across the top of the groove; insulating material placed in
the extended groove on the terminal board; and a magnetic sensitive body
inserted within the insulating material, to which either high frequency
or pulse electic current is applied. When either high frequency or pulse
electrical current is applied to the magnetic sensitive body, voltage is
output from the above electromagnetic coil in response to the intensity
of the external magnetic field which is generated in the electromagnetic
coil.
