A reflective bubble level comprises an elongated level body. The elongated level body comprises a first surface (31) and a second surface (32). A hollow cavity is provided between the first surface (31) and the second surface (32), and provided with an opening on the second surface (32); a level arranged in the hollow cavity comprises a non-opaque level body (1) and a bubble assembly (2), the non-opaque level body (1) being provided with sloping faces (12) and a first observation surface (13); the bubble assembly (2) is arranged inside the level body (1), the longitudinal axis of the bubble assembly (2) is perpendicular to the first surface (31), the first surface (31) is arranged between a first end (21) of the bubble assembly (2) and surface to be checked, and the first observation surface (13) is arranged between a second end (22) of the bubble assembly (2) and a user; the image of the bubble assembly (2) is formed by reflection from the sloping faces (12); and through the first observation surface (13), the user can observe the image of the bubble assembly (2) reflected by the sloping faces (12). In the present reflective bubble level, a reflection is produced when light passes through an interface, so that the user can observe the bubble assembly from the front side while checking perpendicularity. The level is one-step molded and does not require additional assembly and calibration, and therefore is simple to manufacture and low in cost. |
