PROBLEM TO BE SOLVED: To provide a terminal connection structure capable of cutting off the current certainly when an excessive current flows, while securing a constant strength and current flow at a normal time, and a power storage mechanism including this structure, and an electric vehicle. SOLUTION: The terminal connection structure protects a battery when an excessive current flow by disconnecting connection and is provided with a first conductive member 421, a second conductive member 422 connected electrically to the first conductive member 421, and a blow-out part 423 between the first and the second conductive members 421, 422. In this case, the blow-out part 423 comprises a first and a second blow-out parts 423A, 423B formed so as to be arranged in a row along the joining face of the first and the second conductive members 421, 422. Then, the first blow-out part 423A has a relatively higher bonding strength than the second blow-out part 423B, and the second blow-out part 423B has a relatively lower melting point than the first blow-out part 423A.
