<P>PROBLEM TO BE SOLVED: To provide a coating device capable of appropriately controlling a pressure of a coating liquid in a flow passage, and a manufacturing method of an electrode capable of forming the electrode of a high quality with a superior yield by using this. <P>SOLUTION: The coating liquid M is supplied to the flow passage 221 in a coating part 220, and an electrode layer 120 is formed at a current collector 110 by ejecting the liquid from an ejecting hole 222. A retaining groove 241 and a shutoff member 242 are installed at a boundary between the flow passage 221 and the ejecting hole 222. In a process of forming the electrode layer 120, by the contact of a closed face 242A of the shutoff member 242 with the upper wall face 222A of the ejecting hole 222 in the retaining groove 241, shut off is made between the flow passage 221 and the ejecting hole 222. In a process of forming an exposed region 130, by separating the closed face 242A of the shutoff member 242 from the upper wall face 222A, the flow passage 221 and the ejecting hole 222 are communicated. A pressure adjustment valve 252 is opened and closed in cooperation with a shutoff mechanism 240, and the size of a gap between the coating part 220 and the current collector 110 is changed by a moving mechanism 260. <P>COPYRIGHT: (C)2007,JPO&INPIT |
