A level body placed on the surface to be measured is provided with a group of inclination angle indicator lights that illuminate and display the inclination angle of the body, and a conductive pendulum is installed in the level body. A displacement detection sensor that is hung so as to be swingable and is opposed to the pendulum and detects the swing angle of the pendulum, and a voltage change from the displacement detection sensor is detected to detect the inclination angle of the level body. A level that includes a built-in control section that lights up one of the indicator lights of the group of tilt angle indicator lights in response to a detection signal. 2. The spirit level according to claim 1, wherein the pendulum is suspended in a sealed cylinder filled with a damper liquid. 3 Claim No. 1 for Utility Model Registration, in which each indicator light of a group of tilt angle indicator lights is colored differently.
or the spirit level described in paragraph 2.
