PURPOSE: To reduce the manufacturing cost of a photoelectric transducer by moving a laser beam in the direction perpendicular to a transporting direction and irradiating a base material positioned on a transporting roll with the laser beam. CONSTITUTION: A film base material 1 is transported from a delivering roll 2 to a take-up roll 3 through transporting rolls 71, 72, 73. A movable stage 6 which is fixed to the projection port of the laser beam transmitted from an optical fiber 5 is attached to the bearing of the transporting roll 72 through a support 4 to be movable perpendicularly to the transporting direction of the base material 1. Then, the film base material 1 is stopped in the middle of transportation, the laser beam is moved perpendicularly to the transporting direction, the base material 1 positioned on the transporting roll 72 is irradiated with the laser beam, and machining is performed for the thin film on the surface of the base material 1. Thus, a compact and inexpensive device is manufactured. |
