High-sensitivity transparent gas sensor and method for manufacturing the same

A transparent gas sensor comprising:

• a transparent substrate;
• a transparent electrode formed on the transparent substrate;
• and
• a transparent gas-sensing layer formed on the transparent electrode, wherein the transparent gas-sensing layer has a nanocolumnar structure comprising nanocolumns formed on the transparent electrode and gas diffusion pores formed between the nanocolumns,
• wherein the nanocolumns are formed to be inclined with an angle of 60-89° by glancing angle deposition, and the gas diffusion pores are formed in a self-shadowed region where the deposition does not occur.
