PROBLEM TO BE SOLVED: To provide one or more contact probes, having semispherical contact bumps having a height of not less than 1/4 of the diameter each, and to provide its manufacturing method which efficiently forms the bumps in an easy way at a low cost. SOLUTION: One or more contact probes, having semispherical contact bumps 5 each having a height of not less than 1/4 of the diameter are provided to allow the pitch of the bumps 6 to be narrowed, as compared with the conventional bumps 5 each having a height of not greater than 1/4 of the diameter.
