PURPOSE: To keep high function such as strength and abrasion resistance necessary for a tappet for an engine, and reduce processing steps such as heat treatment and mechanical processing for improving producibility.

CONSTITUTION: A tappet for an engine has a cylindrical part 2 provided with an upper wall 1 to be fitted to a fitting hole of a cylinder head, and a circular side wall 6 for fitting to a cam contacting shim, which is formed on an outer peripheral edge of the upper wall 1 continuously to the cylindrical part 2 while being directed upward. In manufacturing such a tappet, a tappet rough body (a) having the cylindrical part 2 provided with the upper wall 1 and the circular side wall 6 is prepared by pressing metal material powder, such that axial measurements of the upper wall 1, the cylindrical part 2, and the circular side wall 6 are larger than those of the tappet to be manufactured. The tappet rough body (a) is sintered, and subjected to re-compression to obtain a final shape.
