1. A cylinder block production method for producing a cylinder block in which a cast iron-made cylinder liner is enclosed within a cylinder block body by casting, comprising:

  • a cast-enclosing step of enclosing the cylinder liner within the cylinder block body by casting; and

    an erosion-wash step of washing an outer peripheral wall surface of the cylinder liner and eroding a portion of a base structure of the cast iron forming the outer peripheral wall surface of the cylinder liner so as to form many small protrusions on the outer peripheral wall surface by jetting a high-pressure fluid onto the outer peripheral wall surface of the cylinder liner, as a step performed prior to the cast-enclosing step in order to improve strength of adhesion between the cylinder liner and the cylinder block body.
