An electrochemical cell has a container housing a separator and a pair of electrodes impregnated with an electrolyte. The container has a base member having a bottom part and a side part disposed on a top surface of the bottom part along an outer rim of the bottom part. A metallic conductive terminal has first and second opposite surfaces penetrating through inner and outer sides of the base member. The first surface of the conductive terminal is disposed on the top surface of the bottom part of the base member. The second surface of the conductive terminal is disposed in contact with one of the pair of the electrodes. A metallic frame member has first and second opposite surfaces, with the first surface being joined to an entire rim of a top surface of the side part of the base member. A metallic cover member is joined to an entire rim of the second surface of the frame member.

An electrochemical cell has a container containing a positive electrode, a negative electrode, and an electrolyte. The container has a bottom face and a hole formed in the bottom face. A positive electrode current collector is embedded in the bottom face of the container so that the hole formed in the bottom face exposes a portion of the positive electrode current collector. A covering portion is adhered to the positive electrode and covers the exposed portion of the positive electrode current collector. The positive electrode current collector is electrically connected to the positive electrode via the covering portion. A lid seals the container.

In an electrochemical cell using a conventional thermally resistant container, there is a problem in that, when it is used at a relatively high voltage, for example, around 3 V, a metal of a collector is dissolved and characteristics thereof are extremely deteriorated. In order to prevent a positive electrode current collector from being dissolved even at a high potential, a surface of the positive electrode current collector is covered by a valve metal or carbon such that the positive electrode current collector and a positive electrode do not come in contact with each other. Therefore, in the electrochemical cell according to the invention, the positive electrode current collector is prevented from being dissolved.

A power source element has a positive electrode case, a negative electrode case, and a pair of connecting terminals, each having a first end portion connected to a respective one of the positive and negative electrode cases, a second end portion for connection to a circuit board, and an intermediate portion disposed between the first and second end portions. The intermediate portion of each of the connecting terminals has a weakened region so that the first end portion is separated from the second end portion along a weakened line in the weakened region upon relative movement between the first and second end portions in a give direction.
