PROBLEM TO BE SOLVED: To provide the electronic balance having an integrated mechanism which can adjust four-corner errors relatively easily and enables reversible adjustment without any possibility of overgrinding, etc., unlike a conventional adjusting method of grinding an elastic fulcrum part with a file. SOLUTION: The electronic balance equipped with an integrated mechanism of one block 10 is provided with a flexible part nearby one elastic fulcrum part 23a between elastic fulcrum parts 23a and 23b at both end parts of an upper or lower beam part 23 of a Roverval mechanism 2 outside the elastic fulcrum parts 23a and 23b, a slit 7 is formed in an area including the flexible part 6 and elastic fulcrum part 23a, and adjusting mechanisms (81, 82, 91, 92, S) which slant the positions A and A' at both the sides of the slit 7 are provided between the elastic fulcrum part 23a and flexible part 6. The positions A and A7 are slanted to shift the effective center position of the elastic fulcrum part 23a up and down, thereby adjusting four-corner errors.
