PURPOSE: To suppress increase in internal pressure of a battery without increase in water repellency of a negative electrode by arranging the negative electrode having a layer mainly comprising Co or a Co compound on the surface of a pasty active material layer mainly comprising a hydrogen storage alloy applied to a conductive core material. CONSTITUTION: A pasty active material is obtained by kneading hydrogen storage alloy powder, conductive auxiliary material, thickening binder, and water. The pasty active material is applied to conductive core material to form an active material layer. A negative electrode having a layer formed by bonding cobalt or cobalt compound powder with a water soluble polymer which is not gelled in an alkaline solution, or polyvinyl alcohol is arranged on the surface of the active material layer. |
