Sensing block to prevent damage to electrode lead

A battery module comprising:

• a battery cell comprising an electrode lead protruding and extending forward;
• a sensing block arranged in front of the battery cell and having a slit through which the electrode lead passes forward and rearward;
• and
• a bus bar mounted on a front portion of the sensing block and on one side in a width direction of the slit, wherein
• the electrode lead is bent toward one side in the width direction at a bent portion located forward of the slit and is connected to the bus bar,
• the sensing block comprises
• a first flat surface connected to one side in the width direction of an inner peripheral surface of the slit,
• a second flat surface on which the bus bar is mounted, the second flat surface protruding forward from one side in the width direction of the first flat surface, and
• a stepped portion provided between the first flat surface and the second flat surface, and
• a boundary where the inner peripheral surface of the slit and the first flat surface meet is formed as a corner having an internal angle of 90 degrees or less.
