Image sensor lens and sensing module with open type

The present invention provides an image sensor lens and a sensing module with an open type. The sensing module includes an image sensing chip, a supporting layer disposed on the image sensing chip, a filtering sheet disposed on the supporting layer, a circuit board having a thru-hole, and an adhesive layer. The supporting layer is not in an enclosed loop-shape and has an inner communication opening. The image sensing chip is soldered and fixed onto the circuit board, and the at least part of the filtering sheet is arranged in the thru-hole so as to jointly form a ring-shaped gap there-between that is in spatial communication with the inner communication opening. The adhesive layer is formed in a part of the ring-shaped gap so as to adhere the filtering sheet onto the circuit board and to form an outer communication opening. Accordingly, the inner communication opening, the ring-shaped gap, and the outer communication opening are jointly formed as a dust-proof channel.
