A nonaqueous secondary battery comprising an electrode body which
comprises a positive electrode and a negative electrode laminated with a
separator interposed between them, and a nonaqueous electrolyte, wherein
said negative electrode comprises graphite as a negative electrode active
material, and has a coating density of at least 1.70 g/cm.sup.3, pore
diameter of the maximum of less than 0.5 .mu.m, and the logarithmic value
of differential intrusion of at least 0.14 cm.sup.3/g at the pore
diameter of the maximum.
