摘要： A bonded object production method according to one embodiment of the present invention involves performing, by using continuous furnace, a process on a laminate that includes a metallic member, a ceramic member, and a brazing material layer disposed therebetween while conveying the laminate. The bonded object production method is characterized by comprising: a step for heating the laminate in an inert atmosphere from 200°C to a bonding temperature at an average temperature increase rate of at least 15°C/min; a step for bonding the laminate in an inert atmosphere at the bonding temperature within a range of 600-950°C; and a step for cooling the laminate from the bonding temperature down to 200°C at an average temperature decrease rate of at least 15°C/min. In addition, the ceramic substrate is preferably a silicon nitride substrate.
