Abstract:
1. An image sensor comprising: a light source that irradiates a light on an object; a lens body that converges a reflection of the light from the object; a plurality of IC chips that receive the reflection passed through the lens body; and a transparent member provided between the IC chips and the lens body and formed continuously over the plurality of IC chips, wherein the transparent member includes a refractive index changing region having a mountain shape or an arc shape, which is provided at a portion opposite to a gap between adjacent IC chips, and a refractive index in the refractive index changing region increases continuously inward toward an inner body of the transparent member in a direction perpendicular to a plane that passes through the plurality of chips so that the refractive index changing region refracts a part of the reflection to be incident into the gap to the IC chips.
