PROBLEM TO BE SOLVED: To provide a digital level utilizing an electrostatic acceleration sensor for slope measurement and adjustment, which is suitable for accurately and promptly conducting vertical measurement of a column, a wall, a panel, etc. in a building structure, etc. SOLUTION: Provided is a digital level utilizing an electrostatic acceleration sensor, wherein a waiting setup means for ensuring stability of the acceleration sensor in starting measurement is installed in a circuit to improve accuracy in measurement, and wherein a calibration (zero point adjustment) is easily performed by reversing the digital level to 180 degrees. An indicator lamp is provided in a display of an angle of inclination thereby to be able to promptly determine an inclination of the column under measurement. In the level, a memory device is provided and an outputting device to a personal computer is provided, enabling the data measured to be recorded, displayed, recalled, deleted, and totally deleted, as well as enabling the data failed to be measured to be recalled and individually deleted.
