The High-pass RC circuit is also known as a differentiator. The name high pass is so called because the circuit blocks the low frequencies and allows high frequencies to pass through it. It is due to reason that reactance of the capacitor decreases with the increasing frequency.

For RC differentiator using opamp, the output voltage is proportional to Lw/R, where w is the angular frequency. From this it can be seen that as frequency increases output increases. Hence its high pass filter.
