[Problem] To be able to easily expand a measurable range, so as to perform both of a long distance measurement and a short distance measurement, and not to perform an incorrect measurement even when a conventional leveling rod for electronic level is mixed and used. [Solution Means] A leveling rod (1) for electronic level has a first pattern (1A) on which a grayscale is formed according to a predetermined rule for a measurement within a first distance range, and a second pattern (1B) which is enlarged or reduced with respect to a pattern (1R) in which the grayscale of the first pattern is inverted for a measurement within a second distance range different from the first distance range. An electronic level includes a height measuring means measuring a height of a collimation point from an output signal from a line sensor so as to correspond to the first pattern, a grayscale inverting means inverting the grayscale of the output signal fromthe line sensor in order to correspond to the secondpattern, and a height correcting means correcting the height measured by the height measuring means according to a reduction scale of the second pattern with respect to the first pattern.
