| 摘要 | The first buffer portion provides a first base portion and a first outer wall provided on a peripheral edge of the first base portion. The second buffer portion provides a second base portion which provides a mounting surface outside to a measurement target, and a second outer wall provided on a peripheral edge of the second base portion. The buffer body provides the first base portion and a top surface of the second outer wall abutting against each other. A housing portion for the sensor portion is provided inside. A holding portion which holds the sensor portion is provided at least at a part of the top surface of at least one of the first buffer portion and the second buffer portion. The sensor portion is held by the holding portion. | ||

| 主权项 | 1. A sensor unit comprising: a buffer body comprising a first buffer portion and a second buffer portion that directly abuts against the first buffer portion and is softer than the first buffer portion; and a sensor portion arranged inside the buffer body; wherein the first buffer portion provides a first base portion and a first outer wall provided on a peripheral edge of the first base portion, the second buffer portion provides a second base portion which provides a mounting surface outside to a measurement target, and a second outer wall provided on a peripheral edge of the second base portion, the buffer body provides the first base portion and the second base portion facing each other and also provides a top surface of the first outer wall and a top surface of the second outer wall directly abutting against each other, and a housing portion for the sensor portion is provided inside, and a holding portion which holds the sensor portion is provided at least at a part of the top surface of at least one of the first buffer portion and the second buffer portion, and the sensor portion is held by the holding portion, wherein the sensor portion is mounted on a substrate, and a peripheral edge portion of the substrate is held by the holding portion such that the peripheral edge portion is abutted by each of the top surfaces of the first and second outer walls to suspend the sensor portion between the first and second buffer portions. | ||
