PROBLEM TO BE SOLVED: To provide a body-weight sensor unit which deals easily with a failure and whose durability reliability is enhanced. SOLUTION: The body-weight sensor unit is constituted in such a way that a body-weight sensor 1 and a body-weight transmission moving element 4 are housed inside a case 2, that the opening of the case 2 is covered with a cap 3, that an outer-circumferential seal packing 5 is installed in the outer circumferential part of the case 2 and that a signal wire which is connected to the sensor 1 is pulled out from a small hole 7 in the case 2 installed on the opposite side of the cap 3 with reference to the packing 5, Thereby, when a test or a quality control operation is performed singly by the sensor unit, or when its service maintenance is performed, the sensor unit is interchangeable, and its application to a device using the body-weight sensor such as a weight-body measuring instrument or the like becomes easy.
