A composite material is produced by a method where an adhesive composition which comprises a particulate material that reduces thermal stress and a brazing material containing a noble metal element as a base, wherein the adhesive composition can bond two or more kinds of different members to form a composite member with sufficient bond strength to avoid causing damages, such as cracks that occur on the side of the member that is weak against thermal stress, and also by a method to produce a composite member comprised of two or more kinds of different members, in which either the adhesive composition is used or the bonding portion of the different members is filled with the particulate material that reduces thermal stress, and then a molten brazing material is poured there into, and cooled to bond the members.
An adhesive composition for bonding two or more kinds of different members which consists essentially of a uniform mixture of a brazing material and a particulate material that reduces thermal stress, wherein a base metal for said brazing material is Au, Ag, Cu, Pd, Al or Ni, and said particulate material is ceramics fine particle, cermet fine particle or low-expansion metal fine particle.
A composite member which comprises two or more kinds of different members differing in thermal stress from each other and an adhesive composition bonding two or more of said different members and comprising a brazing material and a particulate material that which reduces thermal stress.
