Abstract: PROBLEM TO BE SOLVED: To provide an optical modulation element and an optical head device which are high in the availability of light and capable of being manufactured at a low cost by periodically varying the orientation state of crystal in each area where liquid crystal is arranged. SOLUTION: This optical modulating element is decreased in the period of variation in the orientation state of liquid crystal from the center area to the peripheral area 3 so as to have a function similar to that of a Fresnel lens. In this case, the straight line in a concentric circle indicates the orientation direction of the liquid crystal and three layers (3 areas 1-3) are one period. And, the smaller the variation in orientation direction angle between adjacent areas, the better, and the variation is preferably <=45 deg.. In this case, for example, the orientation direction angle is repeatedly 0 deg. (area 1), 45 deg. (area 2), and 90 deg. (area 3) in one period from the center area 1 to the peripheral area 3, and the distribution of the orientation direction angle in one period of 0 deg., 45 deg., and 90 deg. is asymmetrical.  Consequently, the optical modulating element and optical head device which are high in light utilization efficiency and can be manufactured at a low coat and have bifocal lens effect are obtained.
