Laser processing apparatus

A laser processing apparatus that irradiates an object to be subjected to the laser processing with laser light to perform laser processing, the laser processing apparatus comprising:

• a plurality of optical heads, each including a laser head unit that emits a plurality of laser light beams in an arranged manner in a predetermined direction so that the object to be subjected to the laser processing, which is conveyed relatively with respect to the laser head unit in a conveying direction intersecting the predetermined direction, is irradiated with the emitted plurality of laser light beams, wherein
• the plurality of optical heads includes a first optical head group and a second optical head group,
• the optical heads are adjacent to each other in the predetermined direction,
• the first optical head group and the second optical head group are adjacent to each other in the conveying direction and shifted from each other by a predetermined length in the predetermined direction, and
• in each optical head of the first optical head group, the laser head unit is arranged, in the conveying direction, nearer the second optical head group than is a center of the optical head.
