Disclosed is a joint product suitable as a cutting tool that, even when the temperature of a brazing filler metal is raised to an elevated temperature above a liquid phase producing temperature during cutting, does not cause a lowering in joint strength of a joining layer and is suitable, for example, for high-speed cutting and CVD coating treatment. The joint product comprises a cemented carbide sintered compact as a first joining material (1) to be joined and a cBN sintered compact or a diamond sintered compact as a second joining material (3) to be joined. The first joining material (1) and the second joining material (3) are joined to each other through a jointing material (2), which is interposed between the first joining material (1) and the second joining material (3)and does not produce a liquid phase at a temperature below 1000 DEG C. The joining is carried out by electric heating while pressing at pressure of 0.1 MPa to 200 MPa. The first joining material generates heat by heating and is connected prior to the second joining material.
