Claim 7:
8. The liquid crystal element according to claim 7, further comprising
a first circumferential direction lead wire extending in a circumferential direction about the optical axis; and
a second circumferential direction lead wire extending in the circumferential direction, wherein
the first circumferential direction lead wire and the second circumferential direction lead wire are disposed outside of the first arcuate electrodes and the second arcuate electrodes in the radial direction,
one end of the first circumferential direction lead wire is connected to an end of the first radial direction lead wire in the radial direction,
one end of the second circumferential direction lead wire is connected to an end of the second radial direction lead wire in the radial direction,
the first circumferential direction lead wire has a resistance per unit length lower than a resistance per unit length of each of the first arcuate electrodes, and
the second circumferential direction lead wire has a resistance per unit length lower than a resistance per unit length of each of the second arcuate electrodes.
