PURPOSE: A battery pack is provided to improve heat-radiating performance using coolant by comprising a heat-radiant plate with an integrated structure, thereby being capable of improving assembility and reducing weight of a battery module. CONSTITUTION: A battery pack(100) comprises: a battery module(110) which comprises at least one battery cell(10); and at least one heat-radiant plate(120) arranged on a specific position nearby a battery module to touch the battery cell. The heat-radiant plate comprises at least one flow channel which is a channel for coolant, a rib maintaining the structure of the heat-radiant plate, and a thorough-hole part between the channel and the rib. At least one protrusion part is formed on the channel and a connection groove is formed in the ends of the channel. |
