Provided are a multilayer coating apparatus and a multilayer coating method in which an uneven flow can be reduced when two types of resins having different softening points are caused to join together and a wire member is coated therewith. A coating apparatus (10) includes: a first extruder (12) and a second extruder (14); a crosshead (16) for coating a wire member with a resin layer with a double-layer structure; a first nozzle (18) which connects the first extruder (12) and the crosshead (16) to each other; a second nozzle 20 which connects the second extruder (14) and the crosshead (16) to each other; a control unit 22 which controls supply amounts of the first extruder (12) and the second extruder (14); and a heater (24) which heats the second nozzle (20). The second nozzle (20) is longer than the first nozzle (18).
