置。[Claims for Utility Model Registration] 1. A light source comprising a light emitting diode, a collimation lens facing the light source, and a light transmitting member facing the collimation lens, with air bubbles and liquid sealed inside. A bubble tube and a light-receiving element that receives light from a light source that has passed through the light-transmitting member and liquid are arranged in a fixed positional relationship, and the bubble position projected on the light-receiving element is electrically detected and measured. An inclination angle detection device for detecting an inclination angle of an object, characterized in that a light-diffusion treatment is applied to a light-emitting end face of the light-emitting diode. 2. A level tube having a light source made of a light emitting diode, a collimation lens facing the light source, a light transmitting member facing the collimation lens, and having bubbles and liquid sealed therein, and the light transmitting member. and a light-receiving element that receives light from a light source that has passed through the liquid are arranged in a fixed positional relationship, and the position of the bubble projected on the light-receiving element is electrically detected to detect the tilt angle of the object to be measured. What is claimed is: 1. A tilt angle detection device, characterized in that a light-transmitting member subjected to a light diffusion process is disposed between the light source and the collimation lens. 3. The tilt angle detection device according to claim 1 or 2, wherein the light diffusion process is a roughening process.
