A ceramic heater-type glow plug is provided that is configured so that, even when a deformation occurs in a metal outer cylinder, stress propagating to the connection between one electrode of a ceramic heater and an electrode lead-out member can be reduced to prevent the ceramic heater and the electrode lead-out member from being damaged. In the ceramic heater-type glow plug in which heat-resistant insulating particles are sealed into the metal outer cylinder as a sealing material, at least an area around the connection between the one electrode and the electrode lead-out member is filled with a mixed insulating powder mixed with a lubricity enhancing material for improving lubricity among the heat-resistant insulating particles. |
