PROBLEM TO BE SOLVED: To provide a silicon supplying method and device for the base of a cathode-ray tube of such a structure that a pressure rise is sensed by a sensor and the silicon supplying pressure is dropped automatically for supplying an appropriate amount of silicon, as improvement of a conventional technique in which the base is attached to the outer side face of the stem part of cathode- ray tube by adhesion using silicon having a high viscosity involving such a problem that if supplying cathode-ray tube is stopped temporarily by eventual trouble in the manufacturing device in the foregoing process, the standby time till the application of silicon is prolonged to result in a rise of the pressure of the silicon supplying device and an excessive supply of the silicon. SOLUTION: When the base 65 is adhered using silicon to the outer side face of the stem 61 welded to the end part of the neck 57 of cathode-ray tube 64, a pressure gauge 16 is installed in the silicon supply passage, and the motion of the pointer 26 of this gauge 16 is sensed, and the silicon supplying pressure is adjusted automatically by adjusting a decompression valve 14 interposed in the silicon supply passage.
