PROBLEM TO BE SOLVED: To provide a water repellent and oil repellent antifouling composite film solving problems of conventional antifouling chemical absorbent films which use only chemical bonds between the absorbing agent and a surface of a substrate, therefore subjects are scarce in abrasion resistance, and methods using chlorosilane-based surfactant as a treating agent had to be manufactured at an isolated site provided with specific dehydrochlorination equipment since hydrochloric acid is generated in film preparation, or the like. SOLUTION: The solution for preparation of water repellent and oil repellent antifouling composite film is provided by diluting a first substance comprising a fluorinated carbon group containing an organic fluoroether group or organic fluoropolyether group, a hydrocarbon group and an alkoxysilyl group, a second material comprising a fluorinated carbon group, a hydrocarbon group and an alkoxysilyl group, different from the first material and a third material represented by (AO)<SB POS="POST">3</SB>Si(OSi(OA)<SB POS="POST">2</SB>)<SB POS="POST">p</SB>OA (p represents 0 or an integer, A represents an alkyl group, OA may be Cl or NCO), and a silanol condensation catalyst, with organic solvents, and the molecular length of the first material is longer than the molecular length of the second martial.
