To provide an imaging device and an electronic component for the imaging device that are capable of achieving both electromagnetic wave shielding and heat radiation. An external connection connector of a rear housing includes a resin holding portion, and the holding portion includes a case portion connection portion that holds a metal case portion, and a shielding member connection portion that holds a metal shielding member. Accordingly, with a housing including a rear housing, and an imaging device including the housing, heat generated by an electric component can be radiated to the outside effectively with the metal case portion. Furthermore, the metal shielding member can also exert the effect of shielding a pin terminal from electromagnetic waves.
