Abstract
The present invention provides an entry sheet for drilling excellent in hole position accuracy compared with the conventional entry sheet for drilling. Such an entry sheet for drilling is an entry sheet for drilling comprising metallic support foil and a layer comprising a resin composition formed on at least one surface of the metallic support foil, in which the resin composition contains a resin and 70 parts by mass to 130 parts by mass of molybdenum disulfide based on 100 parts by mass of the resin, and the layer comprising the resin composition has a thickness in a range from 0.02 to 0.3 mm.
