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.

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 region having a plurality of first sensors 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 plurality of first sensors being arranged so as to be substantially parallel to the first side,
