<P>PROBLEM TO BE SOLVED: To provide a stereoscopic image photographing device which is capable of reducing the number of parts, inexpensive and excellent in imaging characteristics and to provide an electronic apparatus including the stereoscopic image photographing device. <P>SOLUTION: A stereoscopic image photographing device includes two first lenses L1 and L1 for taking in light from a subject respectively, an optical path composition part (including an optical path conversion element P1) composing the light from the subject taken in by the first lenses L1 and L1 respectively, first to fourth lens groups G1 to G4 imaging the light from the subject composed by the optical path composition part, and an optical path separation part (including an optical path conversion element P2) separating the light after transmitting the first to fourth lens groups G1 to G4, so as to image the light from the subject taken in by the first lenses L1 and L1 respectively on a different image surface. When an optical path length from the incident surface of the optical path conversion element P1 to the first optical path conversion surface P1a is defined as l<SB POS="POST">1</SB>and an optical path length from the first optical path conversion surface P1a to the emission surface of the optical path conversion element P1 is defined as l<SB POS="POST">2</SB>, a condition of l<SB POS="POST">1</SB>≤l<SB POS="POST">2</SB>is satisfied. <P>COPYRIGHT: (C)2012,JPO&INPIT |
