Adhesive tape

An adhesive tape comprising an elongated strip body having:

• an adhesive layer on one side surface of the elongated strip body;
• and at least one perforation line extending between one end edge and an other end edge in a width direction of the elongated strip body, the adhesive tape comprising one side portion and an other side portion adjacent to each other in a longitudinal direction of the adhesive tape with the at least one perforation line therebetween, each of the at least one perforation line being configured to cut off the one side portion from the other side portion, wherein
• each of the at least one perforation line comprises:
• a plurality of separation parts at which the one side portion and the other side portion are separated away from each other in the longitudinal direction of the adhesive tape;
• a connection part through which the one side portion and the other side portion are connected to each other in the longitudinal direction of the adhesive tape, the connection part located between each two of the plurality of separation parts adjacent to each other in the width direction of the adhesive tape;
• and
• a weak connection part through which the one side portion and the other side portion are connected to each other in the longitudinal direction of the adhesive tape, the weak connection part having a smaller breaking strength than the connection part and located between each two of the plurality of separation parts adjacent to each other in the width direction of the adhesive tape but not at which the connection part is located,
• each of the at least one perforation line comprises at least one group comprising the connection part and the weak connection part adjacent to each other in the width direction of the adhesive tape, and
• the weak connection part is formed by half cutting in which the adhesive tape is cut into an intermediate position in a thickness direction of the adhesive tape.
