A photoelectric conversion device is provided which is capable of improving the light condensation efficiency without substantially decreasing the sensitivity. The photoelectric conversion device has a first pattern provided above an element isolation region formed between adjacent two photoelectric conversion elements, a second pattern provided above the element isolation region and above the first pattern, and microlenses provided above the photoelectric conversion elements with the first and the second patterns provided therebetween. The photoelectric conversion device further has convex-shaped interlayer lenses in optical paths between the photoelectric conversion elements and the microlenses, the peak of each convex shape projecting in the direction from the electro-optical element to the microlens.
