The present invention is a sensor having a weight, a frame surrounding the weight, a flexible connector for connecting the weight and the frame, a pressure detector, and an acceleration detector. The weight includes a main portion having a through hole that penetrates from the upper surface to the lower surface of the main portion, an attachment portion connected to the upper surface of the main portion so as to surround the periphery of the through hole, a first lid portion that is flexible and is connected to the attachment portion so as to block the through hole, and a second lid portion that is disposed on the bottom surface of the main portion so as to block the through hole and deforms less in response to force than the first lid. The pressure detector is disposed on the first lid portion and detects, as an electric signal, the bending of the first lid portion resulting from the pressure difference between the enclosed space formed by the main portion, first lid, second lid, and attachment portion, and the outside thereof. The acceleration detector is disposed on the connector and detects the bending of the connector as an electric signal. |
