An absorbent-type moisture sensing module and a moisture sensing sticker having the same are provided. The absorbent-type moisture sensing module includes a silver conductive paste layer, a protective layer and a moisture sensitive material. The silver conductive paste layer includes two conductive sections. A gap is formed between the two conductive sections. The protective layer covers the silver conductive paste layer and has a second gap. The first and second gaps communicate with each other, and they together form a moisture absorbing hole. The moisture sensitive material which can absorb moisture and has conductivity under wet conditions is filled into the moisture absorbing hole. The two conductive sections are electrically connected through the wet moisture sensitive material. The moisture sensing sticker includes a water absorbent layer and multiple absorbent-type moisture sensing modules. Accordingly, the moisture sensing result closely matches the reality.
