A cover sheet ( 1 ) used in a body measuring apparatus having electrodes for supplying current to a human body or for measuring a difference in electrical potential between two sites of the body. The cover sheet has electric conductive area portions ( 2 ) corresponding to the electrodes of the body measuring apparatus and having a electric conductivity in thickness direction, and insulation area portions ( 3 ) spacing adjacent electric conductive area portions ( 2 ) and having electrically insulating property at least along a plane direction. The cover sheet is used to prevent cross-infection and can be used safely without slip and prepared cheaply without affecting to impedance, with assuring completely insulation between adjacent electrodes. Conductivity is created with conductive solid (''dry type'') or conductive liquid (''wet type''). The cover sheet is fed automatically by a sheet dispenser.
