Abstract: PURPOSE:To continuously vacuum-deposit plural kinds of metals on the surface of a strip with high adhesion by arranging plural vacuum deposition devices in series with intermediate ducts and a guide roller in-between and by continuously passing the strip through the devices. CONSTITUTION:A metal 16 such as Ti for vacuum deposition in a crucible 8 in a first vacuum deposition device A is evaporated by heating with an electron beam from an electron beam gun 10.
