PROBLEM TO BE SOLVED: To provide a novel polyimide compound having a high refractive index solely and its manufacturing method. SOLUTION: The polyimide compound is obtained by imidation of a polyimide precursor obtained by an equimolar reaction of an aromatic diamine containing a sulfur linking group or containing a sulfur linking group and a bivalent aromatic group with an aromatic acid dianhydride containing a sulfur linking group and a bivalent aromatic group or containing a sulfur linking group, a bivalent aromatic group and a thiocarbonyl linking group.
