Cell and cell pack
First Claim
1. A battery comprising a single battery (101) or a battery consisting of a plurality of cells connected to one another, a circuit substrate (102) including a protection circuit element for the battery (101) and external terminals, and a resin mold package (103) interposed between the circuit substrate (102) and said battery (101) for uniting said battery (101) and said circuit substrate (102), the protection circuit element being mounted on one side of the circuit substrate (102) opposite one end face of said battery (101) where one of terminals of the battery is disposed, the external terminals (104, 105) being provided on the opposite side from the protection circuit element of the circuit substrate, and said resin mold package (103) covering and providing electrical insulation between said one end face of the battery (101) and said one side of the circuit substrate (102) where the protection circuit element is mounted.

Abstract
A battery and a battery pack comprising a rechargeable battery (2) and a circuit substrate (3) integrated therein by a resin mold package (11) are provided.
Resin is filled between the rechargeable battery (2) and the substrate (3) electrically connected thereto, so as to unite them as one battery or battery pack. The rechargeable battery (2) includes an engaging member (26) which functions as an anchor to the resin mold package (11) formed onto the battery, whereby the resin mold package (11) is firmly joined to the rechargeable battery (2). A thermo-sensitive element can be incorporated either on the circuit substrate (3) or within the space filled with resin.
