Abstract: There is a problem that an area of a principal current cell is reduced by an area of a bonding pad wiring layer for a sub-cell. A source electrode 9b of a current detection cell 22 is electrically connected to a bonding pad wiring layer 12 formed on an interlayer insulating film 10 via a wiring layer contact 11. The bonding pad wiring layer 12 is formed with respect to a source electrode 9a of a principal current cell 21 so as to cover a part of the source electrode 9a via the interlayer insulating film 10. As a result, the source electrode 9b is miniaturized, and a size of the source electrode 9b is made substantially equal to a size of the current detection cell 22. Therefore, the current detection cell 22 and the principal current cell 21 are disposed close to each other.

Abstract: Provided is a recognition device that can accurately recognize a position where a vehicle is to be stopped. The recognition device according to the present invention includes: a distance calculation unit 210 that calculates a map information distance between a host vehicle and a target feature based on map information; a stop line detection processing unit 130a that, in a case where the map information distance is equal to or less than a determination value, sets a detection area for detection of the target feature based on the map information distance, detects the target feature within the detection area, and calculates an actually-measured distance between the host vehicle and the target feature; and a stop line position unifying unit 310 that unifies data of the map information distance and data of the actually-measured distance to calculate a unification result of a distance between the host vehicle and the target feature.
