The conveying speed by the conveyor 130 can be adjusted to any speed between a relatively low first speed at startup and the like and a relatively high second speed at mass production and the like. A region of the conveyor 130 on the downstream side of the energy irradiation section 120 is not irradiated with light energy. That is, in the transporting step, the activated label 3A is adhered from the activated position where the adhesive layer 50 is activated (the position irradiated with light energy by the energy irradiation unit 120) to the spaced position spaced apart from the activated position. The layer 50 is transported in an unactivated state. In other words, in the conveying step, the activated label 3A is conveyed from the activated position to the separated position while reducing the adhesive strength of the adhesive layer 50 thereof.

The sticking step is a step of sticking the activation label 3A to the article B at a spaced position away from the energy irradiation unit 120 . Article B is conveyed by a conveyor or the like. When the conveying speed of the conveyor 130 is the first speed, the pasting step is performed within, for example, 15 seconds from the activation step. 5 or more, and when the conveying speed of the conveyor 130 is the second speed, for example, within 5 seconds from the activation step, that is, the adhesive strength of the adhesive layer 50 is a ball in a special ball tack test. No. It may be implemented when it is 6 or more.
