A method for manufacturing a flexible sheet-shaped material includes a preceding process and a succeeding process. The preceding process is a process for applying a first coating liquid to a material to be coated by a first roll coater. The material to be coated includes a convex portion and becomes the sheet-shaped material. The succeeding process is a process which is performed after the preceding process and which applies a second coating liquid to the material to be coated by a second roll coater. The preceding process is a process for applying the first coating liquid only to the convex portion using a reverse roll coater as the first roll coater. The succeeding process is a process for applying the second coating liquid only to the convex portion by the second roll coater.

A glove coating device capable of supplying a coating layer in which pores are uniformly mixed is provided. The glove coating device includes: i) a dipping bath that is adapted to receive a coating liquid; ii) a coating liquid circulation tank installed in the dipping bath and that is spaced apart from a bottom surface of the dipping bath; iii) an impeller located in the dipping bath and that is adapted to transfer the coating liquid to the coating liquid circulation tank; iv) a motor positioned above the impeller to drive the impeller; and v) a drive shaft extending in the vertical direction to interconnect the motor and the impeller. The coating liquid circulation tank includes i) a first side opened to allow the coating liquid to be introduced; a second side formed on the opposite side of the first side and opened in a direction away from the bottom side to apply the coating liquid to overflow; and a flow passage communicating with the first side and the second side. The flow passage includes i) a first flow passage portion that is adapted to communicate with the first side and having a predetermined width that is smaller than the width of the coating liquid circulation tank, and ii) a second flow passage portion communicating with the first flow passage portion and the second side and gradually widening a width of the second flow passage portion from the first flow passage portion to the second side.
