Abstract
In a fuel injection valve having a housing pipe, a valve movable reciprocatingly and axially inside the housing pipe, and a body valve having a bottom wall constituting a valve seat with which the valve comes in contact and a side wall whose axial end is connected to a circumferential periphery of the bottom wall and whose the other axial end is fitted to and heat bonded to an end of the housing pipe, the side wall is provided on an outer circumference thereof with a ring shaped groove that is formed in advance before the body valve and the housing pipe are heat bonded to each other and serves to prevent a deformation of the side wall due to heat generated by the heat bonding from being transmitted straight to the valve seat.
