Optical laminate and article provided with same

An optical laminate comprising in the following order:

• a transparent base material;
• a hard coat layer;
• an adhesion layer comprising a sputtered film;
• an optical function layer in which high refractive index layers each comprising a sputtered film and low refractive index layers each having a refractive index lower than a refractive index of the high refractive index layer are alternately laminated;
• and an antifouling layer, wherein
• the hard coat layer comprises a silica filler, and
• the optical laminate satisfies condition 1 and condition 2,
• Condition 1:
• A ratio ((A)/(B)) of the Martens hardness (A) measured from the antifouling layer side of the optical laminate to the Martens hardness (B) measured from the hard coat layer side of a laminate having only the transparent base material and the hard coat layer is 3.6 or less, Condition 2:
• A difference in contact angle with respect to water between before and after friction is 20° or less, the friction being performed, using a friction tester with steel wool conforming to JIS L0849, by horizontally reciprocating the steel wool 200 times.
