Abstract
This application provides an optical proximity sensor component that includes an optical proximity sensor and a light guide body. The light guide body includes a first end face. The light guide body is disposed on the optical proximity sensor, and the light guide body is configured to transfer, to the optical proximity sensor, light that enters from the first end face, and send out, through the first end face, light that is emitted by the optical proximity sensor. No additional connector or supporting component is required in the optical proximity sensor, which has a simple structure and is easy to assemble.
