The present disclosure provides a transparent and highly sensitive pressure sensor with improved linearity and pressure sensitivity including: a first substrate on which a micropattern having pyramidal structures is formed; a first electrode layer coated on the micropattern of the first substrate; a second substrate stacked on the first electrode layer; and a second electrode layer stacked on the second substrate, wherein the first substrate and the second substrate show a difference in light refractive index of 10% or less in the visible light region.
