Abstract
The invention concerns a spirit level () including a base body (), e.g., in the form of a hollow profile, as well as a bubble level vial (), formed of a vial body () with enclosed cavity (), preferably of barrel shape, the vial being secured in the base body by means of a holder (). The cavity contains a liquid () with gas bubble () floating therein and the vial body has end face regions () running transversely to the lengthwise axis of the cavity. In order to achieve a high contrast between the end of the bubble and the liquid, it is proposed that the vial body () be joined to the holder () by an intimate material connection in the at least one end face region () and that the holder and/or the intimate material connection be contrast intensifying in the region of the at least one end face region.
