Conventionally, such powder alloy sheets have been bonded by applying an adhesive to the surface of a metal substrate or one side of the powder alloy sheet, and then overlapping the adhesive surfaces before the adhesive properties are lost.

。In the present invention, one component of the two-component adhesive is applied to one side of the powder alloy sheet and the other component to the surface of the metal substrate in advance, and these can be bonded together at any time in the bonding process. workability is significantly improved. Furthermore, the powder alloy sheet and the metal substrate coated with one adhesive component are extremely easy to handle because the powder alloy sheets or the metal substrates do not self-adhere to each other.
