The titanium member has a recess, and the ceramic member has a protrusion coupled to the recess and pores, and the titanium member covers the protrusion of the ceramic member. The protrusion has a cross-sectional area increasing portion whose cross-sectional area increases toward a dead-end portion of the recess in a direction away from a base end of the protrusion. The titanium member is firmly fixed and joined to the ceramic member in a state that a part of the titanium or the titanium alloy is penetrated into the pores of the protrusion of the ceramic member.
