Camera module having a light shieldable layer
A camera module has a sensor chip including a sensor unit formed on a main surface around which sides are disposed. A lens chip is fixed to the sensor chip with a spacer unit and includes a lens unit corresponding to the sensor unit. A light shieldable layer covers a first side of the sensor chip and a side of the spacer unit. A first cutting surface includes a second side of the sensor chip and a side of the light shieldable layer on a same plane.
