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.

A laminated radiation member includes a radiation plate, an insulation substrate bonded to the upper surface of the radiation plate and an electrode provided on the upper surface of the insulation substrate. The laminated radiation member is made by a method including the steps of surface treating a bonding surface of the radiation plate and/or the insulation substrate, interposing ceramic particles surface treated to assure wettability with a hard solder or a metal between the radiation plate and the insulation substrate, disposing a hard solder above and/or below the ceramic particles, heating the hard solder to a temperature higher than the melting point of the solder, penetrating the molten hard solder into spaces between the ceramic particles to react the ceramic particles with the solder to produce a metal base composite material, and bonding the radiation plate and the insulation substrate with the metal base composite material.

The method for measurement of thermal conductivity of a honeycomb structure according to the present invention comprises the steps keeping the whole honeycomb structure in a steady temperature state with keeping two ends of the honeycomb structure at given different temperatures; and measuring a thermal conductivity of the honeycomb structure in the steady state. According to the present invention there is provided a method for measurement of thermal conductivity of a honeycomb structure, which can measure the thermal conductivity of a honeycomb structure in the shape of the honeycomb structure per se or in a predetermined block shape without preparing, for example, a test specimen of particular shape.
