Abstract: A bonded object production method according to an embodiment uses a continuous furnace to process a stacked body including a metal member, a ceramic member, and a brazing material layer located therebetween, while conveying the stacked body; and the method includes a process of heating the stacked body in an inert atmosphere from 200° C. to a bonding temperature at an average temperature raising rate of the stacked body of not less than 15° C./min, a process of bonding the stacked body in an inert atmosphere at the bonding temperature that is within a range of not less than 600° C. and not more than 950° C., and a process of cooling the stacked body from the bonding temperature to 200° C. at an average temperature lowering rate of the stacked body of not less than 15° C./min. A ceramic substrate is favorably a silicon nitride substrate.

Abstract: When the pressure in the battery case is increased, the gas discharge flow rate is secured sufficiently. This battery case (30) is a battery case in which a battery (2) is housed in a housing (10). The battery case (30) includes a gas discharge mechanism (G). The gas discharge mechanism (G) includes a gas discharge port (51) that opens in a wall plate (43) that covers a periphery of the housing (10), and a lid part (35m). The lid part (35m) is disposed to cover the gas discharge port (51) from inside the wall plate (43), and is fixed on the housing (10) side.
