Abstract
Provided is an electronic level capable of accurately measuring a height difference between two points even when a waving method of finding and determining as a measured height a minimum value of read heights while rocking a leveling rod back and forth is used. An electronic level includes leveling rod reading-in means (S2) which reads graduations on a leveling rod being rocked back and forth and stores read heights, and stores the time of reading, approximate function determining means (S3) which approximates the read heights read in by the leveling rod reading-in means by a quadratic function of time, and measured value calculating means (S4) which determines a minimum value of the quadratic function approximated by the approximate function determining means as a measured height.
