To provide an apparatus and a method of heat transfer which can be applied in common to an air-permeable cloth and net, a non-air-permeable waterproof cloth, plastic sheet, real leather or the like or a cloth, sheet, synthetic leather or the like made of a material which has no affinity for a thermosensitive adhesive on a rear face of a heat transfer decorative piece.

An upper surface of a pressure base facing an upper disk for applying pressure and heat to the heat transfer apparatus comprises a vacuum pad with a group of vertically through small pores opened on the upper surface with a highly dense distribution. The inside of the pad is communicated with an intake and pressure-reducing device, an object to be applied with heat transfer is placed on the pad, the heat transfer decorative piece having the thermosensitive adhesive on a rear face is mounted thereon. Pressure and heat is applied by the upper disk, and air is taken from the small pores on the vacuum pad to cause the melted thermosensitive adhesive to enter texture gaps of the object to set.
