To produce a molybdenum sheet in which high-temperature drooping resistance at the evaluation of high-temperature characteristics can be maintained at a value equal to that of the conventional one and also cracks occurring at bending and folding at room temperature can be removed.

The molybdenum sheet contains lanthanum oxide having excellent high temperature characteristics, and also the bending and folding of the molybdenum sheet can be facilitated by controlling the structure of the surface of the sheet after recrystallization. This sheet can be manufactured by: preparing powder obtained by adding La component in the form of a lanthanum nitrate solution to Mo and applying reduction treatment in a hydrogen air flow; preparing another powder obtained by dry-blending Mo powder with the above powder; bringing the resultant two kinds of powder 1 and 2 which are identical in composition and different in powder preparation into contact with each other as in the figure; pressing the above; and sintering the resultant green compact to form the structure of the surface of the resultant sintered compact into microcrystalline grains of 1 to 200 μm.
