Abstract
A medical device including a lubricating coating film (surface lubricating layer) that exerts excellent lubricity and durability is provided. The medical device includes, on a base layer, a surface lubricating layer formed from a block copolymer having a hydrophilic portion and a hydrophobic portion that has a reactive functional group. The ratio of the hydrophobic portion of the block copolymer in an outermost surface of the surface lubricating layer is 20 to 45 mol %, and the viscosity of a 1 wt % chloroform solution of the block copolymer at a temperature of 30° C. is 8 to 30 mPa·s.
