PURPOSE: To obtain the nonaqueous electrolyte cell having a superior discharge characteristic, in particular superior low temperature heavy load characteristic in the last period of electric discharge by regulating the S-value defined as the amount (μl) of electrolyte per active mass (mAH) in positive or negative electrode.

CONSTITUTION: This nonaqueous electrolyte cell is based on the finding that the low temperature heavy load characteristic in the last period of electric discharge is markedly improved in consideration of the balance between the amount of active mass and the amount of electrolyte, and the S-value defined as[amount E(μl) of electolyte/capacity C (mAH) of active mass]is regulated within 0.8≤ S+≤1.3 and 0.8≤S-≤1.2 in which S+≡E/C+, S-≡E/C- for each of positive elec trode active mass C+ and negative electrode active mass C-.
