LEVEL

Provided is a level with which it is possible to check a degree of a horizontal state or a tilt state instantly and clearly by a strip-shaped light-emitter that linearly emits light. The level includes: a sensor 10 that detects a tilt angle; a display unit 2 including a plurality of strip-shaped display members that linearly emits light by an LED to display the tilt angle; and a controller 11 that receives an output signal from the sensor 10 and outputs a control signal so that a specific strip-shaped display member glows. The strip-shaped display members include one horizontal strip-shaped display member 5a positioned at a middle of the display unit and a plurality of strip-shaped display members 5b, 5c,... for tilt-angle display that has tips bent toward a center of the display unit. LEDs 6a, 6b,... are attached to ends of the strip-shaped display members, respectively, and a pair of strip-shaped display members which is point-symmetrical with respect to the center of the display unit simultaneously glows according to the tilt angle.
