Zusammenfassung:	A manufacturing process can be simplified, and manufacturing cost is reduced. A method for manufacturing a ceramic heater-type glow plug (1) that includes: a ceramic heater (11); a metallic outer cylinder (12) that holds the ceramic heater at one end and has the other end inserted in and fixed to a metallic housing (14) ; and lead wire (13) that is connected to the ceramic heater and electrifies the ceramic heater, the method for manufacturing a ceramic heater-type glow plug includes the steps of: forming a metalized layer (116) in a region of the ceramic heater that is connected to the lead wire; press-inserting at least the metalized layer of the ceramic heater in a connection fitting (18) that connects the ceramic heater and the lead wire; and heating the ceramic heater and the connection fitting at a temperature at which a material for forming the metalized layer is brought into a semi-molten state and joining by mass transfer between the connection fitting and a solid layer of the metalized layer.
