Abstract
A coating liquid to be used for coating has a loss tangent tan δ of from 1 to 10 at a frequency of 6.28 radians/sec. A coating liquid supplying roll has a fine concave portion in at least a part of the circumferential length thereof, and in the vicinities of the both circumferential ends of the fine concave portion, the fine concave portionhas concave depth decreasing portions formed in such a manner that the depth of a fine concave decreases. The fine concave portion is constructed in such a manner that the sum L (=L+L) of a circumferential length Lof a portion in which the fine concaves are formed in substantially the same depth and a circumferential length Lof one concave depth decreasing portion becomes an integral multiple (1 or more) of a circumference Lc of the cylindrical substrate.
