<P>PROBLEM TO BE SOLVED: To provide a method of coating in which a fault such as paint coming-off to the rear side of a current collector having holes passing through front and rear surfaces, the generation of thickness unevenness and friction that causes the disconnection of the current collector, does not occur at the coating time of the paint containing an active substance to form an electrode layer on the current collector (porous substrate) having the holes passing the front and rear surfaces. <P>SOLUTION: The method of coating double sides includes a step of providing roll bars 5 in parallel in a shape for sandwiching the porous substrate at paint injection opposed parts of a die to the porous substrate of aluminum, copper, etc. having front and rear surface passing holes, a step of making a liquid reservoir 6 of the paint between the paint injection part of the die and the roll bar, and a step of painting the porous substrate on both front and rear surfaces with the paint containing the active substance. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
