  "textContent": "A decrease in safety due to high-temperature exhaust gas ejected from an opened discharge valve is prevented. In a battery pack, a heat-resistant cap (8) is coupled to an end of a battery block including battery cells (1) each having a discharge valve on an end surface thereof and arranged in plural rows, and is accommodated in a battery case (2). A valve-side end surface (1a) of battery cell (1) is arranged at a first end of the battery block to which heat-resistant cap (8) is coupled. Heat-resistant cap (8) includes closing plate (31) providing a first discharge gap (15A) between the closing plate and end surface (10a) of the battery block, a peripheral wall (32) coupled to a periphery of closing plate (31) and providing a second discharge gap (15B) between the peripheral wall and an outer circumference of the battery block, a partition wall (33) disposed between end surfaces of adjacent battery cells and partitioning the first discharge gap (15A) into portions at end surfaces of battery cells (1). Exhaust gas discharged to the valve-side end surface (1a) passes through discharge gap (15) including first discharge gap (15A) and second discharge gap (15B), and is discharged from an exhaust opening to an outside.",
