PROBLEM TO BE SOLVED: To provide a laser cut-off processing method that enables cut and separation of each cut piece arranged in a plurality of lines and a plurality of rows with no interference of scraps with a laser processing head even when the scraps incline to cause a part to project out of the top face of a work-piece. ! SOLUTION: When a longitudinal common cutting line between each row and a lateral common cutting line between each cut piece in each row are to be processed by laser cutting, the presence of a scrap enables laser cut-off processing in a direction where a work-piece keeps away from the scrap when the scrap is cut and separated from the work-piece without such a laser cut-off processing as to turn round this scrap continuously. !
