A grip force estimation device includes a sensor that is attached to sports equipment including a columnar portion having a grip portion at one end and a hitting portion connected to the columnar portion and is attached not at the grip portion but at the columnar portion, and that is configured to detect at least one of bending and twisting of the sports equipment and output detected bending and/or twisting as a sensor signal, a feature data extraction unit configured to extract feature data including a feature when a waveform generated by the hitting portion being externally applied with pressure is attenuated by using the sensor signal, and a grip force estimation unit configured to estimate pressure applied to the grip portion by using the feature data.
