Claim 14:
15. A magnetic sensor, comprising:
a first sensor part including
a first magnetic member,
a first counter magnetic member, a direction from the first magnetic member toward the first counter magnetic member being along a first direction, and
a first magnetic element including one or a plurality of first extension parts,

a second sensor part including a second magnetic element,
a third sensor part including a third magnetic element,
a fourth sensor part including a fourth magnetic element, and
an element current circuit,
the first extension part including a first magnetic layer, a first counter magnetic layer, and a first nonmagnetic layer,
the first magnetic layer including a first portion, a first counter portion, and a first middle portion,
a direction from the first portion toward the first counter portion being along the first direction,
the first middle portion being between the first portion and the first counter portion,
the first nonmagnetic layer being between the first counter magnetic layer and at least a portion of the first middle portion in a second direction crossing the first direction,
one end of the first magnetic element being electrically connected with one end of the third magnetic element,
an other end of the first magnetic element being electrically connected with one end of the second magnetic element,
an other end of the third magnetic element being electrically connected with one end of the fourth magnetic element,
an other end of the second magnetic element being electrically connected with an other end of the fourth magnetic element,
the element current circuit being configured to supply an element current between a first connection point and a second connection point,
the first connection point being between the one end of the first magnetic element and the one end of the third magnetic element,
the second connection point being between the other end of the second magnetic element and the other end of the fourth magnetic element.
