Zusammenfassung:A low-reflection structure, a lens barrel, and an electronic device are provided. The low-reflection structure includes a light-transmission region and a light-extinction surface arranged around a circumference side of the light-transmission region. Multiple light-extinction groups are disposed at the light-extinction surface, and the multiple light-extinction groups are arranged circumferentially around the light-transmission region. Each light-extinction group has multiple light-extinction structures, and the multiple light-extinction structures of each light-extinction group are all arranged in a radial direction of the light-transmission region.
