[0078] In addition, the above-mentioned embodiment can be implemented or various changes can be added to the above-mentioned embodiment according to the reference example etc. which were given below.
[0079] Insulation components such as image 3 shown. image 3 The heat insulating member is composed of a heat insulating material layer 1 and a heat conducting material layer 2 formed on the heat insulating material layer 1 . Both the heat insulating material layer 1 and the heat conducting material layer 2 are sheet-shaped members, and are bonded to each other with an adhesive. Such as image 3 As shown, both the heat insulating material layer 1 and the heat conducting material layer 2 are rectangular, but the width of the heat conducting material layer 2 is smaller than that of the heat insulating material layer 1 . Furthermore, the heat conduction material layer 2 and the heat insulating material layer 1 are overlapped so that both end edges and one side edge may be share...

[0095] exist Figure 6 In the insulation part of the image 3 There is further a heating device 5 on the heat insulating part. Such as Figure 7 as shown, Figure 6 The heat insulating member has a plurality of heating devices 5 arranged in contact with the heat conducting material layer 2 between the heat insulating material layer 1 and the heat conducting material layer 2 . Between the heat insulating material layer 1 and the heat conducting material layer 2, a heating device 5 is disposed integrally with these layers. Each heating device 5 is connected with a wire 6 for powering the heating device 5 . For example, the heating device 5 is a flexible sheet heater having deformability. The heating device 5 may also be a cord heater.
[0096] and image 3 The insulating part of the same, Figure 6 The heat insulating member is disposed on the secondary battery 3 by disposing the heat insulating material layer 1 on the external heat source side and the heat conducting ma...

[0100] Figure 9 The heat insulating part has: a heat insulating material layer 11 having a plurality of recesses 11a; a heating device 15 arranged at the bottom of the recesses 11a; layer 12; and a wire 16 penetrating through the insulating material layer 11 and connected to the heating device 15. For example, the heat insulating material layer 11 can be formed by molding or excavating a foam having heat insulating properties.
[0101] The recess 11a is formed in a semi-cylindrical shape. And, if Figure 9 As shown, they are arranged in parallel to each other in the heat insulating material layer 11 . Such as Figure 10As shown, the heating device 15 is arranged at the bottom of one end of the recess 11a, and forms a part of the semi-cylindrical bottom of the recess 11a. The heat conduction material layer 12 is arrange|positioned in each recess 11a and its periphery. Furthermore, the heat conduction material layer 12 is arrange|positioned to the other end of the heat in...
