Abstract
This sensor unit includes a base having a substantially-rectangular planar shape including a first side and a second side that are substantially orthogonal to each other, and a plurality of first sensors provided on the base and arranged on a first axis. The first axis is substantially parallel to the first side and passes through a center position of the base.
Claims11
A sensor unit comprising:
- a substrate having a substantially-rectangular shape including a first side and a second side that are substantially orthogonal to each other;
- a circuit chip stacked on the substrate;
- and
- a sensor group provided on a second surface of the circuit chip opposite to a first surface of the circuit chip, the first surface facing the substrate,
- the sensor group having a sensor section that outputs signal in response to changes in an external magnetic field to be detected.
