An electronic balance is provided where precise correction can be carried out by using incorporated weight and the weight and the size can both be reduced. The electronic balance is provided with a main Roberval mechanism R1 for conveying the load of an object to be measured mounted on a scale 16, a first beam 14 to which the main Roberval mechanism R1 is connected, and at the same time, a connection means 43 is connected, a second beam 42 to which the first beam 14 is connected via the connection means 43, and at the same time, an electromagnetic force generating apparatus 17 for generating an electromagnetic force which is balanced with the load of the object to be measured that is conveyed from the first beam 14 is connected, incorporated weight 18 for correction, a sub-Roberval mechanism R2 for conveying the load of the incorporated weight in the vertical direction, and a linking member 44 for conveying the load of the incorporated weight to the second beam 42 via the sub-Roberval mechanism R2, and characterized in that the linking member 44 is connected the second beam 42 on the electromagnetic force generating apparatus 17 side relative to the second fulcrum 41.
