Patent ID: 8613823

Claim:
A method of manufacturing a bonded member in which a first member with which a first bonded surface of flat is formed and a second member with which a second bonded surface of flat is formed are bonded via an intermediate substance that has lost fluidity in predetermined thickness, the method comprising: an arrangement step of arranging a first extended plane and a second extended plane opposing each other in parallel and in such a way that a range where the first bonded surface overlaps with the second bonded surface is equal or smaller than a predetermined range when viewed in a direction of the thickness, the first extended plane including the first bonded surface and a first virtual plane that is flush with the first bonded surface, and the second extended plane including the second bonded surface and a second virtual plane that is flush with the second bonded surface; a first application step of applying the intermediate substance with fluidity onto the first bonded surface; and a movement step of moving the first member to which the intermediate substance is applied, relatively to the second member so that the range where the first bonded surface overlaps with the second bonded surface gradually increases when viewed from the direction of the thickness while a distance between the first extended plane and the second extended plane is maintained and the intermediate substance is filled in a gap formed between the first bonded surface and the second bonded surface.
