Optical ranging module and electronic device

An electronic device, comprising:

• a housing;
• an optical ranging module disposed in the housing, wherein:
• the optical ranging module defines an object side and an element side opposite to the object side, and comprises:
• an optical transmitting unit comprising, in order from the object side to the element side:
• a first optical lens assembly and a light source;
• an optical receiving unit comprising, in order from the object side to the element side:
• a second optical lens assembly and an optical sensor;
• a supporting cap comprising two openings that penetrate from the object side to the element side, wherein the first optical lens assembly of the optical transmitting unit and the second optical lens assembly of the optical receiving unit are respectively disposed in the two openings;
• and
• an optical filter layer being made of a material that only allows infrared light to pass through, and disposed on a light transmitting path of the optical transmitting unit and/or on a light receiving path of the optical receiving unit;
• a driving element disposed in the housing and electrically connected to the light source;
• and
• a control component disposed in the housing and electrically connected to the optical sensor.
