PROBLEM TO BE SOLVED: To sufficiently absorb shock or vibration applied from a pan to a load cell by forming an elastic member interposed between a support frame coupled to a load receive end of the load cell and the pan to be semispherical. SOLUTION: Approximately a center of an X-shaped support frame 16 is coupled to a load receive end 15 of a load cell 14 with a fixed end 13 coupled to a housing 12. Cushion rubbers 17 being an elastic member are fixed in the vicinity of four corners of the support frame 16, while a pan 18 is supported by the cushion rubbers 17. The cushion rubber 17 is semispherical with a semispherical face 19 and a circular plane 20, wherein the circular plane 20 is stuck to the support frame 16 with the semispherical face 19 facing toward the pan 18. When strain occurs on a strain generation part 21 of the load cell 14 corresponding to a weight of an article mounted on the pan 18, a resistance value of a strain gage which generates strain together with the strain generation part 21. A processing circuit converts a change in the resistance value into a change in a voltage value to calculate the weight of the article.
