In order to provide a laminating apparatus in which films can be heated sufficiently, a structure thereof is simple, and films can be loaded easily, a laminating apparatus 1 includes a sheet feed mechanism unit 10 configured to convey a sheet into an apparatus main body 2, a film supply unit 20, a press-bonding mechanism unit 30 configured to perform a thermal press-bonding process while sandwiching the sheet between a pair of films. The laminating apparatus 1 employs a configuration that a state of a sheet feed unit 6 including the sheet feed mechanism unit 10 is appropriately changeable between an open state and a closed state, that the film supply unit 20 includes rollers 25a and 25b at supply positions where the films sufficiently wind around heating rollers 31 and 32 of the press-bonding mechanism unit 30, and that the sheet feed unit 6 includes counter rollers 18 and 19 configured to abut the rollers 25a and 25b in the closed state and separate from the rollers 25a and 25b in the open state.
