Abstract: An astigmatism element converges laser light in a first direction for generating a first focal line, and converges the laser light in a second direction perpendicular to the first direction for generating a second focal line. A light separating element guides the laser light entered into two first areas and into two second areas to four respective positions different from each other, and guides the laser light entered into a third area to a position different from the four positions. When an intersection of two straight lines extending in parallel to the first direction and the second direction and intersecting with each other is aligned with an optical axis of the laser light, the third area is disposed at the intersection of the two straight lines.
