In nuclear fusion reactors, there is the development of high-performance plasma facing components in one of the large problems. Tungsten and CX-2002U were used as an armour material in this research, it was joined in metallurgical with a heat sink material (oxygen-free copper) having the cooling pipe structure, and the divertor simulation test body was produced. Moreover, for the produced test specimen, repetition heat load test was carried out and the heat-resistance, the thermal conductive characteristics and the stability of the joined part were evaluated. Consequently, in the repetition heat load test of 1000 times, the value of the maximum temperature of each part was almost fixed and there was no rapid change, since the stability of the divertor simulation test body was confirmed. However, because the rapid temperature rise of the tungsten simulation test body in the repetition heat load test of 300 times was generated at the surface, it is necessary to examine the connection method furthermore.
