Provided is a balloon coating method and apparatus which can perform coating while freely controlling, for example, the thickness of a coating layer and/or the morphological form of a drug.
The balloon coating method and the balloon coating apparatus (50) are for forming a coating layer (32) on a surface of a balloon (30). The balloon coating method includes: a pulling step of pulling the balloon (30) in the direction of an axis (X) of the balloon (30) to thereby straighten a bend of the balloon (30); and a coating step of rotating the balloon (30) about the axis (X) of the balloon (30), with the balloon (30) maintained in the bend-straightened state, and coating an outer surface of the balloon (30) with a coating liquid (R) containing a drug.
