1. A magnetic sensor, comprising:
a first magnetic part including a first portion, a second portion, and a third portion, a direction from the second portion toward the third portion being along a first direction, the first portion being between the second portion and the third portion in the first direction;
a first magnetic member, a second direction from the first portion toward the first magnetic member crossing the first direction;
a second magnetic part including a fourth portion, a fifth portion, and a sixth portion, a direction from the fifth portion toward the sixth portion being along the first direction, the fourth portion being between the fifth portion and the sixth portion in the first direction;
a second magnetic member, a direction from the fourth portion toward the second magnetic member being along the second direction;
a first element including a first magnetic layer, a distance between the first element and the second portion being less than a distance between the first element and the first portion;
a second element including a second magnetic layer, a distance between the second element and the third portion being less than a distance between the second element and the first portion;
a third element including a third magnetic layer, a distance between the third element and the fifth portion being less than a distance between the third element and the fourth portion;
a fourth element including a fourth magnetic layer, a distance between the fourth element and the sixth portion being less than a distance between the fourth element and the fourth portion; and
