PROBLEM TO BE SOLVED: To provide a battery capable of efficiently radiating heat generated from an electrode body by a simple structure. SOLUTION: This battery 1 is composed of the electrode body 2, a positive electrode terminal 3, a negative electrode terminal 4, a case 5, and an insulation member 6. The positive electrode 3 and the negative electrode 4 have projecting parts 32 and 42 are elastically deformed to press the insulation member 6, respectively. The electrode body 2 with the positive electrode 3 and the negative electrode 4 connected thereto is housed in a body 50 with the insulation material 6 arranged therein. Then the projecting parts 32 and 42 are elastically deformed and press the insulation material 6 against the sidewall of the body 50. Thereby, the positive electrode 3 and the negative electrode 4 are brought into press-contact with the insulation member 6, and bring the insulation member 6 into press-contact with the body 50. Thereby, heat resistance between the positive electrode 3 and the negative electrode 4, and the insulation member 6 and between the insulation member 6 and the body part 50 can be restrained. Accordingly, heat generated from the electrode body 2 can be efficiently radiated by a simple structure. COPYRIGHT: (C)2009,JPO&INPIT
