<P>PROBLEM TO BE SOLVED: To provide an optical element which is excellent in optical efficiency, is compact, and can easily be assembled. <P>SOLUTION: In the optical element in which light transmitted from a light source by a linear light transmission body is irradiated to a recording medium and mounted on a slider moving relatively on the recording medium, the optical element is provided with a fixing part which is formed by a material transmitting light and in which the linear light transmission body is fixed, an incident plane at which light emitted from the linear light transmission body fixed to the fixing part is made incident inside of the optical element, and a deviation plane deviating light made incident from the incident plane, then, the incident plane has optical power converging incident light. <P>COPYRIGHT: (C)2009,JPO&INPIT |
