Abstract: A medical instrument of the present invention includes a hydrophilic processed portion on at least a portion of an outer surface of the instrument. The hydrophilic processed portion contains a hydrophilic polymer and an antibacterial agent, and a water contact angle of a surface of the hydrophilic processed portion is equal to or smaller than 30°. Provided that a silver content per unit area in the hydrophilic processed portion is P, and a silver ion amount per unit area measured by an extraction test described below is Q, P and Q satisfy the relationships of Formula (1) and Formula (2) shown below. Accordingly, the medical instrument has excellent antifogging properties and antibacterial properties and excellently retains the antibacterial properties. 6.0≤P/Q  Formula (1) 15.05≤Q  Formula (2) The unit of P is ng/cm2, and the unit of Q is ng/cm2.
