Abstract
A discrete piece forming device that forms discrete pieces by dividing a work. The device includes a modified part forming unit which forms modified parts in the work having a pre-pasted adhesive sheet containing swell grains which swell by application of a predetermined energy, to form, in the work, predefined discrete piece areas each surrounded by the modified parts. The device further includes a dividing unit which divides the work into pieces by forming, in the work, cracks starting from the modified parts by applying external force to the work, to form the discrete pieces. The dividing unit applies the energy to parts of the adhesive sheet to swell the swell grains contained in adhesive sheet parts to which the energy has been applied, thereby displacing the predefined discrete piece areas pasted on the adhesive sheet parts to form the discrete pieces.
