The invention relates to a highly heat-resistant laminated component -1- for a fusion reactor consisting at least of a plasma-facing area -2- made of tungsten or a tungsten alloy, a heat-dissipating area consisting of copper or a copper alloy with a mean grain size of more than 100 .mu.m -4- and an interlayer -3- consisting of a refractory metal-copper-composite, whereby the refractory metal-copper-composite exhibits a macroscopically uniform copper and refractory-metal concentration progression and a refractory metal concentration x of 10 vol.% < x < 40 vol.% over its entire thickness.
