Abstract
A load cell has a cantilever-type load-sensitive element with an upper beam and a lower beam, each having formed thereon a pair of strain-generating parts which generates a strain corresponding to an applied load. Only one of these two beams has an indented part formed on its surface and strain-detecting elements are attached to its bottom surface at positions corresponding to the strain-generating parts. A moisture-proof sheet is attached to the beam to completely seal the interior of this indented part to protect the strain-detecting elements from humidity and moisture.
