An object is to provide a novel level in which a mounting base can be pressingly fixed in a container case in a reliable manner by a simple operation while having a simple configuration, wherein the level has excellent mass-productivity and is advantageous in terms of cost. The level is composed of a mounting base 2 provided with a bubble tube measuring portion 1 in which a liquid and a bubble are sealed, or a mounting base 2 provided with a magnetic body 10 is disposed inside a container case 3, and an opposing end portion 2a of the mounting base 2 is pressed to the inner surface of the container case 3 to cause the mounting base 2 to be pressingly fixed inside the container case 3 in a prescribed position in which the bubble tube measuring portion 1 can be viewed from a window hole 4 provided to the container case 3, or in a prescribed location that allows the magnetic body 10 to be exposed from an exposure hole 14 provided to the container case 3, the level being one in which the mounting base 2 is configured so that a first unit 2A that presses against the inner surface of one side of the container case 3 and a second unit 2B that presses against the inner surface of the opposing opposite side of the container case 3 are slidably assembled by way of a slide mechanism S; the slide mechanism S is formed so that the assembly contact surfaces 5 and 6 of the first unit 2A and second unit 2B are formed as slope guide surfaces 5 and 6; the slope guide surfaces 5 and 6 make contact with each other, the second unit 2B is slidably configured in the slope direction in relation to the first unit 2A, and the entire length of the mounting base 2 composed of the first unit 2A and second unit 2B is variably configured; and the entire length of the mounting base 2 performs a micromotion when the second unit 2B performs a sliding micromotion in relation to the first unit 2A via pressing means P that presses the second unit 2B against the first unit 2A of the mounting base 2 to cause the mounting base 2 to be pressingly fixed inside the container case 3.
