Magnetic sensor

A magnetic sensor comprising:

• a die pad;
• and
• a first magnetoelectric conversion unit which detects a magnetic field and converts it to an electrical signal, a second magnetoelectric conversion unit which detects a magnetic field and converts it to an electrical signal, and a signal processing unit which processes signals output from the first magnetoelectric conversion unit and the second magnetoelectric conversion unit, which are provided on a first face side of the die pad;
• wherein the die pad includes:
• a first frame portion extending along a first direction;
• a second frame portion extending along the first direction and facing the first frame portion in a second direction which intersects with the first direction, and spaced apart from the first frame portion;
• a coupling portion extending along the second direction and coupling the first frame portion and the second frame portion;
• and
• a third frame portion and a fourth frame portion extending along the second direction between the first frame portion and the second frame portion and arranged facing each other across the coupling portion, and
• wherein the first magnetoelectric conversion unit and the second magnetoelectric conversion unit are arranged facing each other in the first direction across the coupling portion between the third frame portion and the fourth frame portion in a plan view,
• the first frame portion includes a fifth frame portion on the third frame portion side relative to the coupling portion and a sixth frame portion on the fourth frame portion side relative to the coupling portion,
• the second frame portion includes a seventh frame portion on the third frame portion side relative to the coupling portion and an eighth frame portion on the fourth frame portion side relative to the coupling portion,
• at least one of the third frame portion, the fifth frame portion, or the seventh frame portion has a first gap which reaches to a first space portion surrounded by the coupling portion, the third frame portion, the fifth frame portion, and the seventh frame portion from an outer edge, and
• at least one of the fourth frame portion, the sixth frame portion, or the eighth frame portion has a second gap which reaches to a second space portion surrounded by the coupling portion, the fourth frame portion, the sixth frame portion, and the eighth frame portion from an outer edge.
