Lens attached substrate, layered lens structure, camera module, manufacturing apparatus, and manufacturing method

A method of manufacturing a lens substrate, the method comprising:

• forming a through-hole and a notched portion at a light-emitting end of a sidewall of the through-hole in a substrate;
• forming a light-shielding film on the sidewall of the through-hole;
• and
• forming a lens portion within the through-hole such that the lens portion contacts the light-shielding film formed on the sidewall of the through-hole.

An electronic apparatus comprising:

• a plurality of lens substrates, each lens substrate of the plurality of substrates including:
• a substrate including a through-hole and a notched portion at a light-emitting end of a sidewall of the through-hole;
• a light-shielding film disposed on the sidewall of the through-hole;
• a lens portion disposed inside the through-hole of the substrate;
• and
• a sensor substrate that includes an optical sensor.
