The utility model provides a terminal lead and electrochemistry equipment adopting the same. The terminal lead (1) is provided with an inner end part (1a) assembled on the inner side of an exterior body (9) for accommodating an electrochemistry element (6), an outer end part (1b) assembled on the outer side of the exterior body, and a platy metal base material (2) using as a base material; an insulating resin film (4) is arranged at the part, corresponding to a sealing part (9x), of the exterior body, in the terminal lead; surface coating layers (3) are arranged on two surfaces (2p and 2p) in the thickness direction of the metal substrate (2); the amount of coating on two end parts (3a and 3a) in the width direction of a surface coating layer (3) at two end parts (2pa and 2pa) in the width direction on the two surfaces (2p and 2p) in the thickness direction of the metal substrate (2) is less than that of the coating at the middle part (3b) in the width direction of the surface coating layer (3) of the middle part (2pb) in the width direction on the two surfaces (2p and 2p) in the thickness direction of the metal substrate (2).
