Abstract
According to one embodiment, an optical element is provided with a paraelectric crystal, first and second pressers between which the paraelectric crystal is sandwiched, and fasteners. The paraelectric crystal has a periodic structure in which polarities are periodically inverted along a polarity period direction. The fasteners fix the first and second pressers to each other so that a predetermined pressure is applied in a direction intersecting with the polarity period direction, to the paraelectric crystal through the first and second pressers.
