PROBLEM TO BE SOLVED: To provide a strain gauge type load cell having a plurality of sensitive parts improved in strength to other shafts and heightened in the degree of freedom in the mechanical connection of the sensitive parts while reducing the flexure quantity of the sensitive parts of low capacity and high sensitivity. SOLUTION: Sensitive part structure is formed as a parallel plate system to heighten mechanical rigidity to multiple shafts, and a plurality of sensitive parts are connected by a combination of fitting and fastening with screws, or fixing with screws to heighten the degree of freedom in mechanical connection. Notching or boring is applied to the sensitive parts of low capacity and high sensitivity to concentrate stress thereon. Specified output can thereby be obtained, and the quantity of flexure can be reduced.
