Provided is an optical layered body which sufficiently suppresses generation of interference fringes and curls, can make a hard coat layer thin, and prevent an increase in production cost. Provided is an optical layered body having a hard coat layer formed on one surface of a light-transmitting substrate, wherein the hard coat layer has a surface roughness on its surface and the surface roughness satisfies the following inequalities of θa and Kr where θa is an average inclination angle of the uneven part and Kr is Kurtosis of the unevenness: 0.01°≦θa≧0.10° 1≦Kr≦3.
