液面検出器。[Claims for Utility Model Registration] A light-emitting side transparent body and a light-receiving side transparent body are arranged facing each other while maintaining a liquid entry space, and a light-emitting element is provided on the outer end side of the light-emitting side transparent body, and a light-emitting side transparent body is provided on the outer end side of the light-emitting side transparent body. In a liquid level detector in which a light-receiving element is provided on the outer end side of a transparent body, the light-emitting element and the light-receiving element are integrally attached to the outer ends of the light-emitting side transparent body and the light-receiving side transparent body, respectively,
and at least the interface with the liquid of the transparent body on the light emitting side,
When there is no liquid in the liquid entry space, the light from the light emitting element is totally reflected at the interface, and when there is liquid in the liquid entry space, the light from the light emitting element is passed through the liquid from the interface and from the transparent body on the light receiving side. A liquid level detector characterized in that it is formed on an inclined surface having an angle to allow light to enter a light receiving element.
