Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a nickel-cadmium battery and a nickel-metal hydride battery that are excellent in quick charging characteristic and the battery life by suppressing the buildup of internal pressures during charging, without inhibiting the charging reactions of negative electrodes. SOLUTION: This sealed secondary battery has a negative electrode whose surface has a contact angle of not more than 110 deg. and not less than 75 deg. within one minute after an electrolyte has been dropped and a contact angle of not more than 80 deg. and not less than 65 deg. 15 minutes after the electrolyte has been dropped.
