Abstract
The load-sensitive element of a load cell is provided with reduced-thickness portions for endowing the cell with flexibility, and a strain gauge is bonded to each reduced-thickness portion. A deposited aluminum tape or a deposited aluminum film, comprising a substrate and a deposited aluminum layer provided on the substrate, is bonded over each strain gauge by using an adhesive, thereby covering each strain gauge with a deposited aluminum layer. Alternatively, each strain gauge is covered with aluminum foil or a deposited aluminum film bonded in place through the intermediary of a rubber sheet interposed between the load-sensitive element and the foil or film, a space being provided around the strain gauge. Furthermore, the strain gauge is covered by a Teflon sheet non-adhesively, and further, a covering member such as a deposited aluminum film or tape covers the strain gauge from the top of the Teflon sheet.
