Abstract
A negative electrode 10 for a nonaqueous secondary battery, has an active material layer 2 containing active material particles 2a. The active material layer 2 has a metallic material 4 deposited among the particles by electroplating. The negative electrode 10 has a large number of holes 5 open on at least one side thereof and extending through the thickness of the active material layer. The negative electrode 10 further has a pair of current collecting layers 3a and 3b adapted to be brought into contact with an electrolyte. The active material layer 2 is between the current collecting layers 3a and 3b. The holes 5 open on the negative electrode 10 preferably have an opening area ratio of 0.3% to 30%. At least one of the pair of the current collecting layers 3a and 3b preferably has a thickness of 0.3 to 10 μm.
