A polyimide resin includes an acid anhydride residue; and a diamine residue, the polyimide resin including a residue of a polysiloxane diamine represented by Formula (1) in an amount of not less than 60% by mole in the total amount of the diamine residue: n n n n n n n n n n wherein, n is a natural number and an average value thereof calculated from the average molecular weight of the polysiloxane diamine is 45 to 200; R 1 and R 2 , the same or different, each represent an alkylene group having 1 to 30 carbon atoms or a phenylene group; and R 3 to R 6 , the same of different, each represent an alkyl group having 1 to 30 carbon atoms, a phenyl group or a phenoxy group. |
