ABSTRACT:
A load cell comprises a column elastic body 11; a circle bore 12 formed on a center portion of a first end surface 11a of the column elastic body 11, a bottom wall of which constitutes a load acting surface 13; an annular concave groove 15 formed on a second surface 11b of the column elastic body 11 being coaxial with the circle bore 12, a bottom portion of which constitutes a strain occurrence portion 18, a outer portion of which constitutes a fixing portion 16 of thick cylinder configuration; and Strain gages stuck on the strain occurrence portion. A distance "y" from the load acting surface 13 to a surface of the strain occurrence portion 18 is 0.2 to 2 times shortest distance "e" from a center axis of the column elastic body to the strain gages.
