Prepared is a film including at least one surface having a friction property having A of not less than 0.01 and B of not greater than 0.6, A and B being values obtained from friction testing, wherein

the friction testing includes measuring relative dynamic friction coefficients of the at least one surface at various moving speeds v (mm/s) of a contact probe, creating a plot of log(v), log(v) being a common logarithm of the moving speed, on a horizontal axis and on a vertical axis and performing linear fitting to obtain a straight line, and

A is a slope of the straight line and B is an intercept of the straight line. The tactile film includes a tactile layer, which is formed of a cured product of a curable composition including a curable resin and is disposed on the outermost layer; and the surface of the tactile layer may have a friction property having a slope A of 0.01 or higher and an intercept B of 0.6 or lower. The curable resin may include a (meth)acrylic polymer having a polymerizable group, a urethane (meth)acrylate, a silicone (meth)acrylate, and a cellulose ester. The curable composition may include no fine particles. The tactile layer of the film may be laminated on a substrate layer formed of a transparent resin. The film has excellent finger slidability.
