An electronic balance including a first Roberval's chain, a second Roberval's chain connected to the first Roberval's chain, and a detector. The first Roberval's chain includes a first fixed pillar, a plurality of first beams, and a first movable pillar supported by the first fixed pillar via the plurality of first beams. The first beams extends substantially in parallel with each other and in a first extending direction. The first movable pillar is configured to receive a load to be measured. The second Roberval's chain includes a second fixed pillar, a plurality of second beams, and a second movable pillar supported by the second fixed pillar via the plurality of second beams. The plurality of second beams extends substantially in parallel with each other and in a second extending direction substantially perpendicular to the first extending direction of the plurality of first beams. The second movable pillar is connected to the first movable pillar. The detector is configured to detect the load electrically via a movement of the first movable pillar.
