Abstract: An optical film having high anti-glare properties and favorable fingerprints wiping off properties is provided. The optical film has a first surface, and a second surface which is a surface opposite to the first surface, wherein the optical film comprises an anti-reflection layer and an anti-glare layer in this order from the first surface to the second surface, the first surface has a profile of depressions and projections, the first surface has an arithmetic mean height Sa of 0.05 μm or more specified in ISO 25178-2:2012, and the first surface satisfies the relation represented by the following Expression 1: Sw×Vmp≤2.00 (Expression 1) wherein “Sw” represents a tilt angle (degrees) of 30 μl pure water droplet flowing down on the first surface; and “Vmp” represents a value of a peak material volume (ml/m2) of the first surface specified in ISO 25178-2:2012.

Abstract: The present invention aims to provide an adhesive composition which enables achievement of highly strong adhesion between a lightweight composite resin and a lightweight metal member, and which can maintain excellent adhesive strength even in cases where the ambient temperature largely changes or the adhesive composition is in contact with water or a snow-melting agent, and an adhesive sheet using it. The above object can be achieved with an adhesive composition containing at least an epoxy resin, an acrylic particle, and a curing agent, wherein the acrylic particle is a core-shell structure containing a butadiene-based rubber, and polymethacrylate or polyacrylate. The adhesive sheet is constituted such that an adhesive layer formed with the adhesive composition is present between a first release film and a second release film.
