An electrodeposition solution comprising an electrodeposition material including
at least an electrodepositive polymer material, which comprises hydrogen atoms,
and capable of forming an electrodeposition film by depositing the electrodeposition
material from the electrodeposition solution, wherein 10% to 90% of the hydrogen
atoms are substituted by heavy hydrogen atoms and a transmission loss of the electrodeposition
film to light in a wavelength region of 700 nm to 1,350 nm is no more than 1 dB/cm.
