Abstract: PURPOSE:To heat a card only during ultrasonic oscillation, to cool the card quickly by an ultrasonic oscillation head when oscillation is stopped and to obtain a uniform frost in specified depth by executing frost treatment by the ultrasonic oscillation head. CONSTITUTION:A card 1 is placed on a cradle 3, and a head 2 is lowered and the card 1 is held. When the head 2 is ultrasonic-oscillated under the state, the recording surface of the card 1 is heated only during the oscillation, and frost-treated. When oscillation is stopped, heating is stopped. Since head 2 itself is not heated and is brought to a temperature near to normal temperature at all times, the frost-treated recording surface is cooled by the head 2, and a frost, in which no frost returns and which has specified depth, is obtained. The frost treatment is executed at a temperature higher than the glass transition temperature (Tg) of the resin of a smooth layer 11 and lower than the melting point (Tm) in order to retain distortion.
