Disclosed are an electrochromic material containing a π-electron based conjugated polymer that changes from a desired color developed state to a decolored state and a method for producing the same. The electrochromic material contains a π-electron based conjugated polymer as shown in chemical formula (1).
(in the formula: each X is any one selected from —S—, —O—, —Se— and —Te—; each Y is any one selected from a hydrogen atom and an organic group having 1 to 20 carbon atoms; W is an arylene group or divalent heteroaromatic ring group; n is a number of 2 to 1,000, and repetition of this structure forms a structure of random copolymers, graft copolymers, block copolymers and/or dendrimers.)
