Abstract (en)
[origin: EP3135998A1] To simplify a structure and a manufacturing process of a ceramic heater-type glow plug so as to cut manufacturing cost. A manufacturing method of a ceramic heater-type glow plug (1) including: a ceramic heater (11); and a metallic outer cylinder (12), one end of which holds the ceramic heater and the other end of which is fixed to a housing (14) has: a step of forming a metallized layer (116) on at least a portion of a surface region in the ceramic heater that is held by the outer cylinder (12); a step of press-inserting at least the metallized layer of the ceramic heater in the outer cylinder; and a step of heating the ceramic heater and the outer cylinder at a temperature at which a material for forming the metallized layer becomes a semi-molten state and performing joining by mass transfer between the outer cylinder and a solid layer of the metallized layer.
