A dental implant including a columnar core member and a covering layer which is covered over at least part of the outer circumferential surface of the core member and which is comprised of recrystallized apatite-based ceramic, wherein the covering layer is comprised of a hydrothermal treated layer of a plasma spray-deposited covering which is formed by spraying a plasma of a composite containing at least two types of calcium phosphate-based compounds which differ in melting point at the outer circumferential surface of the core member based on the melting point of the low melting point calcium phosphate-based compound among the calcium phosphate-based compounds. This dental implant is provided with a strength enabling it to sufficiently withstand a chewing force over a long period of time and with a fast bondability and affinity with the gum and furthermore is excellent in extraction strength as well.
