Gripping tool, gripping system, and method for manufacturing resin member

According to one embodiment, a gripping tool includes a gripper, a sensor, a pump unit, and a controller. The gripper is flexible and has a granular material provided in an interior of the gripper. The sensor is connected to the interior. The sensor detects a pressure or a flow rate of a gas. The pump unit is connected to the interior. The controller performs at least a first operation of causing the gripper to contact a workpiece and causing the gripper to operate, and a second operation of separating the gripper from the workpiece and causing the gripper to operate. In at least a portion of the second operation, the controller sets a pressure of the interior to be different from a pressure external to the gripper.
