The present teaching provides a water repellant and oil repellant film composition comprising a siloxane compound represented by formula (1) or a cured product of the siloxane compound.




(In formula (1), each R1 denotes at least one atom or group that is selected from the group consisting of a hydrogen atom, organic groups having 2 to 10 carbon atoms and a carbon-carbon unsaturated bond that is able to be hydrosilylated, and alkyl groups having 1 to 10 carbon atoms, each R2 denotes at least one atom or group that is selected from the group consisting of a hydrogen atom, organic groups having 2 to 10 carbon atoms and a carbon-carbon unsaturated bond that is able to be hydrosilylated, and alkyl groups having 1 to 10 carbon atoms (the R2 groups in a single molecule may be the same as, or different from, each other). Each R3 denotes at least one atom or group that is selected from the group consisting of a hydrogen atom, organic groups having 2 to 10 carbon atoms and a carbon-carbon unsaturated bond that is able to be hydrosilylated, and alkyl groups having 1 to 10 carbon atoms (the R3 groups in a single molecule may be the same as, or different from, each other), each R4 denotes an alkyl group having 1 to 6 carbon atoms, and at least some of the R2 groups or at least some of the R3 groups are hydrogen atoms and organic groups having 2 to 10 carbon atoms and a carbon-carbon unsaturated bond that is able to be hydrosilylated. w and x each denote a positive number, v, y and z each denote 0 or a positive number, and the value of x/(v+w+x+y) is 0.2 or more.)
