Abstract
According to the present disclosure, a coated member is provided with a base material and a diamond layer located on the base material. When a ratio (SP3/SP2) obtainable from an SP3 peak derived from diamond crystals measurable by Raman spectroscopy and an SP2 peak derived from a graphite phase is referred to as an SP3 ratio, an SP3 ratio at a first measuring point with a thickness up to 1 μm extending from an interface of the base material and the diamond layer toward the diamond layer is higher than an SP3 ratio at a second measuring point that is intermediate in a thickness direction of the diamond layer.
