HEART RATE DETECTION MODULE AND ELECTRONIC DEVICE

A heart rate detection module and an electronic device are disclosed. The heart rate detection module includes a substrate, and a light source, an optical receiver, a light blocking portion, and an optical film that are disposed on the substrate. The light blocking portion is disposed between the light source and the optical receiver, so that the light source is optically isolated from the optical receiver. The optical film covers the light source, the light blocking portion, and the optical receiver, and a light filtering portion is disposed on a side that is of the optical film and that faces the substrate.
