1. A method for monitoring a transfer state of a liquid used in a sample measuring device transferred in a flow path having at least two liquid holding portions, the method comprising:
transferring the liquid held in a first liquid holding portion to a second liquid holding portion connected to the first liquid holding portion;
completing transfer of the liquid from the first liquid holding portion to the second liquid holding portion;
acquiring information related to scattered light intensity obtained by irradiating light on an inner surface having irregularities of at least one of the first liquid holding portion and the second liquid holding portion after the transfer of the liquid is completed and the flow of liquid has stopped; and
monitoring a state of the liquid transferred to the second liquid holding portion based on the information related to the scattered light intensity.
