Provided is an impact point estimation apparatus for estimating an impact point on a face surface of a head when a golf club having a grip, a shaft and the head is swung and hits a golf ball. The apparatus has an acquisition unit, a calculation unit, and an estimation unit. The acquisition unit is configured to acquire time series sensor data that is output from at least one of an angular velocity sensor and an acceleration sensor that is attached to at least one of the grip and the shaft. The calculation unit is configured to calculate a characteristic value of an initial stress wave that occurs due to impact from the sensor data acquired in an analysis period including an initial period after impact. The estimation unit is configured to estimate the impact point on the face surface, according to the characteristic value. The analysis period is before a predetermined short time period has elapsed from impact.
