To improve the strain gauge load cell, in load measurement accuracy by preventing its temperature from getting uneven.

A load transducing section 51, which measures a load applied from an arm 4, is coupled to the arm 4 through an upper radiating section 521 coupling with the arm 4 by using a ball joint disposed on its upper edge, and through an upper heat insulating section 522, whose upper edge couples with the lower edge of the upper radiating section 521 and whose lower edge couples with the upper section of the load conversion section 51. Furthermore, the load conversion section 51 is supported on a base 1 through a lower radiating section 531 coupling with the base 1 by using a ball joint disposed on its lower edge, and through a lower heat insulating section 532, whose lower edge couples with the upper edge of the lower radiating section 531 and whose upper edge couples with the lower section of the load conversion section 51.
