<p><P>PROBLEM TO BE SOLVED: To provide a mechanism for efficiently radiating heat generated in an imaging element while miniaturization of an imaging apparatus is maintained and for making heat of a main circuit board difficult to be transmitted to the imaging element. <P>SOLUTION: An imaging apparatus includes: a radiation duct 26 in which an exhaust port and an inlet port are installed, and which includes an air circulation path for exhausting air taken in from the inlet port to the outside of an apparatus body from the exhaust port. The air circulation path is communicated with the outside of the apparatus body 1 but is not communicated with the inside of the apparatus body. The radiation duct 26 is arranged between a rear face of a light receiving face of an imaging element 23 and a main circuit board 27 on which an electronic component is mounted. A member 26b on an imaging element 23 side is formed of a material whose heat conductivity is higher than that of a member 26a on the main circuit board 27 side. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
