The present invention relates to a composite comprising a structural part, a porous part, and at least two interconnecting parts arranged at a distance from each other and extending from the structural part to the porous part, thus connecting them to each other. The implant is characterized in that each interconnecting part is in the form of a band having a length, a width and a height, the width and the height both being independently at most 20% of the length of the band, and in that at least one of the interconnecting parts is at least partially embedded into the structural and porous parts.
