Abstract
This solid-state image capturing device includes a light receiving element, a charge holding region, and a floating diffusion region that are arranged in a semiconductor substrate, and the light receiving element, a first transfer gate, and a second transfer gate in the semiconductor substrate, and is configured to have a potential gradient in the charge holding region such that signal charges that have been transferred from the light receiving element to the charge holding region by the first transfer gate are distributed more on the second transfer gate side than on the first transfer gate side.
