PURPOSE: An image sensor and a method for manufacturing the same are provided to be capable of improving photo sensitivity by minimizing the difference of focusing point between the center portion and edge portion of a microlens. CONSTITUTION: After forming a pixel having a light receiving element(22) on a substrate(20), an interlayer dielectric(23) and a metal wire(24) are sequentially formed on the resultant structure. A passivation layer(25) is formed on the resultant structure. A focusing point compensation layer(26) is formed on the passivation layer. A planarization layer(27) is formed on the resultant structure. A microlens(28) is then formed on the planarization layer. At the time, the focusing point compensation layer(26) has a different index of refraction compared to the planarization layer.
