The invention discloses a PTC (Positive Temperature Coefficient) electric heating tube and an electric vehicle water heater. The PTC electric heating tube comprises a heating body, electrode plates, solid insulation layers, isolation sheets and a metal tube, wherein the two electrode plates serially connect the multiple solid insulation layers provided with PTC heating sheets and an isolation sheet arranged between each adjacent solid insulation layers and are placed in the metal tube; each solid insulation layer is an insulated ceramic hollow porcelain knob; the PTC heating sheets and the electrode plates are tightly attached through a drawing process; certain deformation space is left in the insulated ceramic hollow porcelain knob; and in the case of drawing, the PTC heating sheet can be prevented from being squeezed in the case of deformation of the metal tube and the insulated ceramic hollow porcelain knob and can be prevented from being damaged. Insulated ceramic material is used to serve as an insulation layer, and thermal efficiency and working reliability of the electric heating tube are improved. Through the drawing process, the contact surface of each part of the electric heating tube is tighter, and heat transfer effects and seismic resistance performance are enhanced. Through design on the structure of the inner cavity of the insulated ceramic porcelain knob, the inner part of the porcelain knob can have enough deformation space, and the PTC heating sheet can be prevented from being squeezed in the case of deformation of the metal tube and the solid insulation layer and can be prevented from being damaged.
