To provide a terminal connection structure which can extend a creepage path while controlling an enlargement of a terminal base.
A first insulation layer 311 and a second insulation layer 321 are formed between a barrier rib 40 and a positive electrode terminal 31 and the barrier rib and a negative electrode terminal 32 respectively, and a first terminal lamination portion 41 and the second lamination portion 42 are formed between the barrier rib 40 and the positive electrode terminal 21 and between the barrier rib and the negative electrode terminal 22 respectively. Corresponding to the degree at which the first and the second insulation layers 311, 321 are formed, a creepage path L11 is extended. Furthermore, corresponding to the degree at which the first and the second terminal lamination portions 41, 42 are provided, the creepage distance L12 has a sufficient length as a conventional one. As a result, an occurrence of a short circuit is controlled between the positive electrode terminals 21, 31 and the negative electrode terminals 22, 32 respectively. Furthermore, in order to extend the creepage paths L11, L12, it is not necessary to increase a thickness of the barrier rib 40, for example.
