PROBLEM TO BE SOLVED: To provide an electronic balance reduced in affection of vibration force in a perpendicular direction to the line connected with action points of measurement weight and electromagnetic force. SOLUTION: On the end face of the movable column 4 of the weight measurement cell 1 of a block shape, two lateral holes 1a, 1b are provided. Between the lateral holes 1a and 1b a point of force spring 11 is provided, also inner side surfaces between the lateral holes 1a and 1b are formed as inner edge faces of the fulcrum springs 13a and 13b, the vertical hole 1c is bored from up side or bottom side of the weight measurement cell 1, and both the longitudinal side faces of the weight measurement cell 1 are formed by dividing the fulcrum springs 13a and 13b in the vertical direction.
