An electron gun (5) for a cathode-ray tube (1) comprises a dish-shaped control electrode (25'). The electrode is made from three separate components: a substantially planar component (61) drilled with apertures (43, 44) so as to allow the passage of electron beams (6, 7, 8), and two identically shaped components (60, 66) intended to make a skirt serving as a support for the cathode modules (21, 22). The components (61, 60, 66) are welded together. This structure allows the contruction of a control electrode serving as support for cathode modules by virtue of inexpensive components which are simple to manufacture.
