PROBLEM TO BE SOLVED: To provide a solid-state image sensor and an electronic camera suitable for focus detection without using a high-level pixel interpolation process or a complicated optical system.SOLUTION: The solid-state image sensor includes: a first imaging device disposed on a first substrate having a first photo-electric conversion part for converting a first color light in incident light and transmitting the rest of the incident light and a second photo-electric conversion part for converting a second color light and transmitting the rest of the light; and a second imaging device disposed on a second substrate having a third photo-electric conversion part for converting a third color light transmitted through the first photo-electric conversion part and a fourth photo-electric conversion part for converting a fourth color light transmitted through the second photo-electric conversion part. The first substrate and the second substrate are laminated; and the first color light and the third color light, and the second color light and the fourth color light are in the relation of complementary colors.SELECTED DRAWING: Figure 7 【課題】 高度な画素補間処理や複雑な光学系を用いることなく、焦点検出に適した固体撮像装置および電子カメラを提供する。【解決手段】 固体撮像装置は、入射光のうち、第１色の光を光電変換して残りの光を透過する第１光電変換部と、第２色の光を光電変換して残りの光を透過する第２光電変換部と、を有する第１基板に設けられる第１撮像素子と、第１光電変換部を透過した第３色の光を光電変換する第３光電変換部と、第２光電変換部を透過した第４色の光を光電変換する第４光電変換部とを有する第２基板に設けられる第２撮像素子と、を備える。第１基板と第２基板とは積層配置され、第１色の光と第３色の光、及び、第２色の光と第４色の光は、それぞれ補色の関係である。【選択図】 図７
