A coating agent that has excellent durability and a medical instrument (for example, a needle) that has been coated with the coating agent, are provided. The coating agent includes a condensate (1) of a compound represented by the following general formula (1-1) with a compound represented by the following general formula (1-2), n na polydiorganosiloxane (2), and an amino-group-containing polyorganosiloxane (3). The content ratio of the polydiorganosiloxane (2) is 30 to 75 mass %, based on the total mass of the condensate (1), the polydiorganosiloxane (2), and the amino-group-containing polyorganosiloxane (3). |
