PURPOSE: A cathode ray tube is provided to prevent an influence of the magnetic field to the electron beams emitted from an electron gun by improving each structure of an inner shield and a funnel. CONSTITUTION: A phosphor layer is formed on the inside of a panel(50). A shadow mask assembly is formed with a shadow mask(61) and a frame(62). The shadow mask(61) is installed at predetermined position apart from the phosphor layer of the inside of the panel(50). The frame(62) is coupled with a stud pin and installed in the inside of the panel(50). A funnel(70) is formed with a neck portion(71) and a cone portion(72). The funnel(70) is coupled with the panel(50). An electron gun and a deflection yoke are installed at the funnel(70). A magnetic shielding portion(80) is formed at the funnel(70).
