There is provided a skin condition estimating apparatus which allows a user to know a skin condition by more sensory characteristics. In impedance measuring means 101, a contact impedance and an internal impedance are measured. In biological equivalent model associated parameter estimating means 102, parameters associated with an equivalent model constituting a living tissue are estimated based on the measured internal impedance. In skin condition estimating means 103, a skin condition is estimated based on at least one of the measured contact impedance, the measured internal impedance, and the estimated parameters associated with an equivalent model constituting a living tissue.
