Claim 6:
7. The laser processing apparatus according to claim 1, wherein
the irradiation portion includes:
a first laser processing head configured to emit a first laser light as the laser light; and
a second laser processing head configured to emit a second laser light as the laser light,
in the first process, relatively moves the part of the focusing region of the first laser light along the first region to form the modified region and stops formation of the modified region in a region of the line other than the first region, and
in the second process, relatively moves the part of the focusing region of the second laser light along the second region to form the modified region and stops formation of the modified region in a region of the line other than the second region, and
the adjustment portion
adjusts, when the first process is performed, an orientation of a longitudinal direction of a shape of the part of the focusing region in a plane orthogonal to an optical axis of the first laser light to be the first orientation, and
adjusts, when the second process is performed, an orientation of a longitudinal direction of a shape of the part of the focusing region in a plane orthogonal to an optical axis of the second laser light to be the second orientation.
