Abstract
An image sensor includes: 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. The transparent member includes a refractive index changing region provided at a portion opposite to a gap between adjacent IC chips. A refractive index in the refractive index changing region increases continuously or stepwise toward an inner portion of the transparent member from a surface of the transparent member on an IC chips side so that the refractive index changing region refracts a part of the reflection to be incident into the gap to the IC chips.
