Abstract
A processing device forms, in an object to be processed, a modified spot constituting a modified region. The processing device includes a first irradiation unit configured to irradiate the object with first light to temporarily increase absorptivity in a partial region of the object as compared with the absorptivity before irradiation of the first light, and a second irradiation unit configured to irradiate the partial region with second light in an absorptivity increase period in which the absorptivity of the partial region is temporarily increased.
