Claim Text:
1. An oscillating type physical property measuring apparatus equipped with an oscillator, wherein an end part of the oscillator is shaped as a sphere, the oscillating type physical property measuring apparatus comprising: the oscillator; an oscillation driving unit adapted to cause the oscillator to oscillate; a probe including a sensor for detecting acceleration of the oscillator; a driving signal output unit adapted to output a driving signal to the oscillation driving unit so that driving forces when the end part respectively oscillates in the air and in a fluid-correspond to predetermined values; and calculation means for calculating a viscosity and/or a density of the fluid, based on a predefined mechanical impedance of the probe including the oscillator and on an amplitude ratio and a phase difference of accelerations detected by the sensor when the end part respectively oscillates in the air and in the fluid.
