To provide a cast iron member for cast-in insert whose adhesion with an aluminum material matrix can be improved compared with the conventional cast iron member for insert casting for a cylinder liner or the like.

The cast iron member is used for insert casting working using a high pressure aluminum die casting process, and is provided with a modification coating layer for improving its adhesion with an aluminum material on the surface, and also, its surface roughness (Ra) is 5 to 150 m. Then, as the modification coating layer, an aluminum based coating layer, a magnesium based coating layer, a tin based coating layer, a zinc based coating layer or a copper based coating layer is used. Further, for formation of the modification coating layer, a production method using metal foil is provided.
