Disclosed are: a coating solution for forming an antireflective coating film which has good adhesion to a substrate without any surface treatment, excellent scratch resistance, low refractivity, low haze and high transmissivity; a method for producing the coating solution; a cured film and an antireflective film produced by using the coating solution; and an antireflective substrate having the cured film. The coating solution is characterized by comprising a polysiloxane (A) which has an organic group bound to the main chain composed of a polysiloxane (a), wherein the organic group has a mercapto group bound thereto via a siloxane bond.
