Abstract:
The present invention relates to a transmission type target having a diamond base material as the transmissive base material. The transmission type target includes a target layer containing a metal carbide constituted of at least one metal selected from the group consisting of molybdenum, tantalum, and tungsten and carbon; and a diamond base material supporting the target layer. The transmission type target inhibits the composition of the target layer from varying with the drive history of the transmission type target and inhibits the output of radiation from varying over a long time.
