Disclosed is a method for laser-cutting a carbon fiber base, e.g., a preform configured of sheets of fabric comprising carbon fibers, characterized by cutting the carbon fiber base under initial conditions which have been set so that the state of the base that is being cut with a laser can be inhibited or prevented from deviating from the desired state. With the method, it is possible to effectively eliminate various problems including dissipation of heat, positional shifting from the focal length range of the laser, and soot, and the carbon fiber base can be stably cut while being kept in the desired state. |
