PURPOSE:To gain a color picture tube in which a close contact heaping of a contact spring is prevented and a drop down of the contact spring owing to a weak welding is avoided, by forming projections at the plane portion of the contact spring. CONSTITUTION:A contact spring 7 is formed with a frame fixing member 7a to fix to a mask frame 2 at one end, a funnel contact member 7b of a circle arc form to contact to a funnel at the other end, and a connecting member 7c between the frame fixing member 7a and the funnel contact member 7b. At the frame fixing member 7a is formed a projection 7d projecting at the opposite side of the mask frame 2, and at the connecting member is also formed a projection 7e. These projections 7d and 7e are made at the same time as the contact spring 7 is made. Therefore, the close contact heaping of the contact spring 7 is prevented, always only one spring is spot-welded 8 to the mask frame 2, and a trouble that the contact spring drops down owing to a weak welding is avoided.
