Metal particle and method for producing the same, coated metal particle, metal powder

Provided are metal particles configured from Cu and trace elements, in which the grain diameter of the particles is 10-1,000 [mu]m, the mass ratio of Cu as measured by GDMS analysis exceeds 99.995%, and the total mass ratio of P and S among the trace elements is 3-30 ppm. Also provided is manufacturing method including: a step for melting, in a crucible, a metal material in which Cu exceeds 99.995% as measured by GDMS analysis and the total of P and S is 3-30 ppm to produce a molten metal material; a step for applying a pressure of 0.05-1.0 MPa inside the crucible, and dropping the molten metal material from an orifice 5-1,000 [mu]m in diameter, to produce molten metal droplets; and a step for rapidly solidifying the molten metal droplets in an inert gas having an oxygen concentration of 1,000 ppm or less to produce metal particles having a grain diameter of 10-1,000 [mu]m.
