A method of producing a forged part includes holding a material by a jig, upsetting the material, held by the jig, to a predetermined length by a pair of upsetting dies disposed on both ends of the material, while pressing the upsetting dies on the material, so as to produce large-diameter portions at the respective axial ends of the material. Next, a bending operation and a forging operation are made to the upset material, in that order. When forging, a direction, in which the material is forged, is set, so that a burr generated on the material by upsetting is included in a burr generated on the material by forging. Next, a finish-machining operation is made to the forged material to remove the burr left on the outer periphery of the material after forging. Thereafter, the finish-machined material is drilled to form bush-mounting holes in the large-diameter portions.

An intake valve 10 of an internal combustion engine, eg a gas-fuelled engine, has an uneven portion 14 formed on a flared slope portion 12 having a slope which gradually expands from the valve stem (11, fig.1) toward the valve seat portion13, and in which a slope angle of the flared slope portion 12 changes at the uneven portion 14. An oil-repellent coating layer 20, eg with fluorine, is formed on at least part of the flared slope portion 12 including the uneven portion 14 to level unevenness at the uneven portion 14 to reduce deposits where they might otherwise adhere or accumulate. The coating layer 20 may be applied also to part of the valve stem 11. The thickness of the coating layer 20 may change between the uneven portion 14 and the valve stem. The uneven portion (14A, fig.3) may comprise two steps. The flared slope portion (12B, fig.4) may be concave.
