Abstract
A sensor unit includes: a substrate including a first coupling portion disposed on a first surface and a second coupling portion disposed on a second surface; a first sensor module including a first coupled portion that is located on a side close to the first surface and that is coupled to the first coupling portion, a first acceleration sensor, and a first angular velocity sensor; and a second sensor module including a second coupled portion that is located on a side close to the second surface and that is coupled to the second coupling portion, a second acceleration sensor, and a second angular velocity sensor.

A sensor unit comprising:
- a substrate including a first surface and a second surface, which are in a front and back relationship, and including a first coupling portion disposed on the first surface and a second coupling portion disposed on the second surface;
- a first sensor module including a first coupled portion that is located on a side close to the first surface and that is coupled to the first coupling portion, a first acceleration sensor, and a first angular velocity sensor, the first coupled portion being disposed on the first surface;
- and
- a second sensor module including a second coupled portion that is located on a side close to the second surface and that is coupled to the second coupling portion, a second acceleration sensor, and a second angular velocity sensor, the second coupled portion being disposed on the second surface,
- wherein the first sensor module and the second sensor module are disposed such that a center of the first sensor module and a center of the second sensor module overlap each other in a plan view of the substrate, wherein
- the first sensor module and the second sensor module overlap each other in the plan view of the substrate, and
- when four quadrants are defined by a first virtual line and a second virtual line that intersect with the center of the first sensor module and are orthogonal to each other in the plan view of the substrate,
- the first coupled portion and the second coupled portion overlap each other in one quadrant in the plan view of the substrate, and
- each of the first sensor module and the second sensor module include a common signal wiring that is disposed in the quadrant where the first coupled portion and the second coupled portion overlap each other and that is common to the first sensor module and the second sensor module, and an individual signal wiring that is disposed in a quadrant where the first coupled portion and the second coupled portion do not overlap and are individual to the first sensor module and the second sensor module.
