The packaging bag 100 includes a transparent soluble sheet 101 that is melted by the heat of the heater 31 and can be viewed internally, and an opaque insoluble sheet 102 that is not melted by the heat of the heater 31 and cannot be viewed internally. For example, the transparent fusible sheet 101 is formed of pet polyethylene or the like, and the opaque insoluble sheet 102 is formed of non-woven fabric, paper or the like.

  The user 200 confirms the position of the content 110 and seals the packaging bag 100. As a result, the packaging bag 100 is sandwiched between the main body 2 and the movable body 3 with the transparent fusible sheet 101 positioned on the upper side and the opaque insoluble sheet 102 positioned on the lower side. Then, when the movable body 3 is properly positioned with respect to the main body 2, the heater 31 is energized.

  Thereby, since the heater 31 generates heat, the packaging bag 100 is heated. At this time, the heater 31 can heat the transparent soluble sheet 101 without interposing the opaque insoluble sheet 102. Therefore, since the sealing device 1 according to the present embodiment can seal the object 100 under appropriate heating conditions (heating temperature, heating time), for example, the conventional sealing device in which the heater 31 is disposed only in the main body 2 On the other hand, for example, the life of the heater 31 can be extended or the power consumption at the heater 31 can be reduced.

  And electricity supply to heater 31 is stopped by passing predetermined time. At this time, since the insulator 34 has thermal insulation, the heat of the heater 31 is prevented from being conducted to the support 33. Thereby, the heat of the heater 31 is reliably released from the heat dissipation unit 21 via the glass tape 37, the packaging bag 100, the glass tape 23, and the silicon sheet 22. Thereafter, the movable body 3 is separated from the main body 2 after a predetermined time has elapsed, whereby the sealing of the packaging bag 100 is completed.

  The connector 38 a is connected to the support 33 so as to be movable with respect to the support 33 in response to the expansion and contraction of the heater 31 in the longitudinal direction. Further, the biasing body 38 b applies a tensile force in the longitudinal direction to the heater 31 in order to bias the connecting body 38 a. As a result, the tension mechanism 38 having the connection body 38 a and the biasing body 38 b can continuously apply the tensile force to the heater 31 which is expanded and contracted in the longitudinal direction.

  Further, in the sealing device 1 according to the present embodiment, the connection body 38 a is fixed to the second electrode 31 b of the heater 31, and the second electrode 31 b of the heater 31 and the support 33. In order to insulate from, it has composition of having insulation.
