To provide a metal microparticle generating apparatus which can suppress the reduction in the production capacity of metal microparticles with the lapse of time, and to provide a hair care apparatus provided therewith.

A discharge electrode 2 is formed by a wire rod. Since the thickness of the wire rod is almost constant in the longitudinal direction, even if its tip is rounded by discharge, its radius of curvature can be easily maintained to be small; thus, a degree of electric field concentration is easily maintained to be in a strong state, and the reduction in capacity of producing metal microparticles can be suppressed.
