Bonded body manufacturing method and bonded body

Abstract

A method of manufacturing a bonded body includes: a preparation step of interposing a sealing material (6) containing glass between a highly thermal conductive substrate (2) and a glass substrate (3); and a bonding step of forming a sealing layer (4) by irradiating the sealing material (6) with laser light (L). The bonding step includes: a first heating step of preheating the sealing material (6) at a temperature lower than a softening point of the sealing material (6) or a temperature at which the sealing material (6) is prevented from softening and flowing by irradiation with the laser light (L); and a second heating step of heating, after the second heating step, the sealing material (6) at a temperature equal to or higher than the softening point of the sealing material (6) or a temperature at which the sealing material (6) softens and flows by irradiation with the laser light (L).
