The present invention relates to a waterproof substrate, and an object of the present invention is to provide a waterproof substrate capable of blocking a liquid such as water and transmitting matter waves and gases such as gas, sound waves and light through a micrometer-sized minute hole. To this end, the waterproof substrate of the present invention comprises micro holes that has pores of size on the order of micrometers and penetrates through both surfaces of the waterproof substrate, wherein a portion of a surface of the waterproof substrate at least in the vicinity of the minute hole is made of a hydrophobic material. Additionally, at least one of the both surfaces of the waterproof substrate is formed with protrusions around the minute hole. With the lotus effect due to the protrusions, it is possible to realize super water-repellency of the waterproof substrate itself. |
