Claim 7:
8. A sensing apparatus, comprising:
a sensing device;
a first light-transmitting protective layer, located on the sensing device;
a light-shielding layer, located on the first light-transmitting protective layer, and the light-shielding layer having a pinhole corresponding to the sensing device;
a patterned light-transmitting adhesive layer, located on the first light-transmitting protective layer and at least located in the pinhole; and
a light guide device, disposed on the patterned light-transmitting adhesive layer and corresponding to the pinhole, wherein a refractive index of the patterned light-transmitting adhesive layer is greater than a refractive index of the light guide device, wherein a portion of the light-shielding layer does not overlap with any one of the patterned light-transmitting adhesive layer and the light guide device,
wherein the patterned light-transmitting adhesive layer physically contacts the first light-transmitting protective layer, and the refractive index of the patterned light-transmitting adhesive layer is greater than a refractive index of the first light-transmitting protective layer.
