Sensor and inspection device

A sensor, comprising:

• a first magnetic member;
• a first counter magnetic member, a direction from the first magnetic member to the first counter magnetic member being along a first direction, a first gap being provided between the first magnetic member and the first counter magnetic member;
• a first magnetic element including a first magnetic region, a second direction from the first magnetic region to the first gap crossing the first direction;
• and
• a first magnetic interconnect, a direction from the first magnetic interconnect to the first magnetic region being along the second direction,
• wherein
• the first magnetic interconnect includes a first partial region and a second partial region,
• a direction from the first partial region to the second partial region is along the first direction, and
• a first thickness of the first partial region along the second direction is different from a second thickness of the second partial region along the second direction.
