A periscopic camera module, comprising: a first reflective element, which is used to reflect incident light, being a light incident on the entire periscopic camera module, and make it turned, wherein the incident direction of the incident light defines a longitudinal direction, and wherein the first reflective element is mounted on a first base; an optical lens, which is used to receive the light reflected by the first reflective element and output an imageable light beam to an image side, wherein the optical lens is mounted on a second substrate; a second reflective element, which includes at least one second reflecting surface adapted to, in a direction perpendicular to the longitudinal direction, laterally turn the imageable light beam at least once, wherein the second reflective element is a second prism, and the second reflecting surface is located on a side surface of the second prism, and the second prism is mounted on a third substrate, and the surfaces of the second substrate and the third substrate are both perpendicular to an incident direction of an incident light; and a photosensitive chip, which is adapted to receive the imageable light beam laterally turned by the second reflective element, wherein the photosensitive chip is adhered to a fourth substrate, and a surface of the fourth substrate is parallel to the incident direction of the incident light; characterized in that the second reflective element includes multiple groups of the second reflecting surfaces, and each group has two second reflecting surfaces which are parallel to each other, and any two adjacent groups of the second reflecting surfaces are arranged in a "V" shape or an inverted "V" shape, and a cross-section shape of the second prism is formed by splicing multiple "V" or inverted "V" shapes. a first reflective element, which is used to reflect incident light, being a light incident on the entire periscopic camera module, and make it turned, wherein the incident direction of the incident light defines a longitudinal direction, and wherein the first reflective element is mounted on a first base; an optical lens, which is used to receive the light reflected by the first reflective element and output an imageable light beam to an image side, wherein the optical lens is mounted on a second substrate; a second reflective element, which includes at least one second reflecting surface adapted to, in a direction perpendicular to the longitudinal direction, laterally turn the imageable light beam at least once, wherein the second reflective element is a second prism, and the second reflecting surface is located on a side surface of the second prism, and the second prism is mounted on a third substrate, and the surfaces of the second substrate and the third substrate are both perpendicular to an incident direction of an incident light; and a photosensitive chip, which is adapted to receive the imageable light beam laterally turned by the second reflective element, wherein the photosensitive chip is adhered to a fourth substrate, and a surface of the fourth substrate is parallel to the incident direction of the incident light; characterized in that the second reflective element includes multiple groups of the second reflecting surfaces, and each group has two second reflecting surfaces which are parallel to each other, and any two adjacent groups of the second reflecting surfaces are arranged in a "V" shape or an inverted "V" shape, and a cross-section shape of the second prism is formed by splicing multiple "V" or inverted "V" shapes.
