To provide a method for producing a steel component integrally having a rubber portion without necessity to remove by a lathe turning a film formed on the surface of a steel component by a chemical conversion treatment and without deterioration of water-resistant adhesive property and anti-corrosion property during production steps due to omission of the chemical conversion treatment, the method for producing a steel component integrally having a rubber portion includes the steps of subjecting a surface of a steel component to a chemical conversion treatment with iron phosphate as a ground treatment (step S3), partially coating an adhesive on a portion to which a rubber portion is to be bonded (step S4), and bonding the rubber portion via baking to the steel component (step S5).
