Disclosed are a transparent film having excellent appearance quality and an adhesive film equipped with the transparent film. Specifically disclosed is a transparent film (10) which comprises a base layer (12) compose of a transparent resin material and a topcoat layer (14) provided on a first surface (12A) of the base layer (12). The topcoat layer (14) has an average thickness (Dave) of 2 to 50 nm and a fluctuation (?D) in thickness of 40% or less of the average thickness (Dave). L'invention porte sur un film transparent dont l'aspect est d'excellente qualité, et sur un film adhésif pourvu du film transparent. Plus particulièrement, l'invention porte sur un film transparent (10) qui comporte une couche de base (12) constituée d'un matériau en résine transparent et d'une couche de revêtement supérieur (14) disposée sur une première surface (12A) de la couche de base (12). L'épaisseur moyenne (Dave) de la couche de revêtement supérieur (14) est de 2 à 50 nm et la fluctuation (?D) de l'épaisseur est d'au plus 40 % de l'épaisseur moyenne (Dave).
