PROBLEM TO BE SOLVED: To provide a functional molecular element whose function is controlled by an electric field based on a new principle. SOLUTION: To a linear or filmy standard molecule 2 having a conjugated system and displaying electrical conductivity, a Lewis base molecule 14 having a positive dielectric constant anisotropy or having a dipole moment in a transverse direction of the molecule is arranged in the shape of a pendant through the aid of a metal ion 3 functional as a Lewis acid, thus forming a functional molecular element 1 that demonstrates its function while a conformation changes due to application of an electric field. The conductive standard molecule 2 and the Lewis base molecule 14 form the metal ion 3 and complex 6. For example, if the electric field is applied in a direction orthogonal to the paper as shown in figure (b), the Lewis base molecule 14 performs an oscillating motion of 90<SP>o</SP>with the vertical direction of the paper as an axis. Further, if the electric field is applied in a vertical direction of the paper as shown in figure (c), it performs a seesaw movement with a direction orthogonal to the paper as an axis, switching the electric conductivity of the conductive standard molecule 2.
