PCT No. PCT/JP96/01660 Sec. 371 Date Sep. 19, 1996 Sec. 102(e) Date Sep. 19, 1996 PCT Filed Jun. 17, 1996 PCT Pub. No. WO97/00374 PCT Pub. Date Jan. 3, 1997This invention aims at providing a sliding component having a crowning shape formed by applying surface quenching treatment to a portion made of a steel, and a production method thereof. The shape and the quantity of crowning can be controlled by heat-treatment or machining after the surface quenching. The sliding component may be made of a steel alone, or may be formed in such a manner that at least one portion of members forming the crowning-shaped sliding face by the surface quenching is joined or fitted to a sliding component main body made of the steel, and its material is a ceramic.
