The present invention relates to a cowl cross member with improved bonding strength. The cowl cross member with the improved bonding strength of the present invention comprises a hollow cowl crossbar and an injection member provided on the outer surface of the cowl crossbar by an insert injection method. The entire outer circumference or a partial outer circumference of the cowl crossbar in the longitudinal direction is knurled or coated with an adhesive so as to increase a frictional force with the injection member. An objective of the present invention is to provide the cowl cross member with the improved bonding strength, configured so that the plastic injection member does not flow on the outer surface of the cowl crossbar.
