A balloon control apparatus, comprising: an insertion part to be inserted into a luminal part a balloon provided at a distal end of the insertion part a pipeline connected to the balloon a pump that flows a fluid to the balloon via the pipeline an intermittent device that causes the pump and the pipeline to be intermittently disconnected/communicated, thereby restricting the flow of the fluid a pipeline pressure detection device that detects a pipeline internal pressure of the pipeline a flow amount calculation device that calculates a flow amount of the fluid at the time of a next communication of the intermittent device based on the pipeline internal pressure at a reached value of the pipeline internal pressure in a disconnection period of the intermittent device and an intermittent operation control device that controls an intermittent operation in the intermittent device based on the flow amount of the fluid calculated by the flow amount calculation device.
