Connecting structure of terminals

A connecting terminal structure allows providing additional terminals without an increase in the width of a battery pack (30; 60) and an electric apparatus (10; 70). In a connecting terminals structure according to the present invention, a battery pack (30; 60) is provided with a plurality of terminals (45, 46) having different functions arranged in a sliding direction, and an electric apparatus (10; 70) is provided with a terminal (23s) to be connected to one of the plurality of terminals (46) of the battery pack (30; 60). Through relative sliding between the battery pack (10; 70) and the electric apparatus (10; 70), before the terminal (23s) in the electric apparatus (10; 70) reaches the terminal (46) in the battery pack (30; 60), the terminal (23s) in the electric apparatus (10; 70) can pass through another terminal (45) in the battery pack (30; 60).
