The invention discloses an optical path turning element, a camera module and an electronic device. The optical path turning element comprises a first surface, a second surface, a first reflecting surface and a second reflecting surface, light enters the light path turning element from the first surface. The second surface and the first surface are correspondingly arranged in a first direction and are parallel to each other, and the first direction is perpendicular to the first surface. The first reflecting surface is connected with the first surface and the second surface, an acute angle is formed between the first reflecting surface and the first surface, and light is internally reflected through the first reflecting surface. And the light is subjected to another internal reflection through the second reflecting surface. The light path turning element further comprises a shading structure, and the shading structure extends from at least one of the first surface and the second surface to the inside of the lig
