Claims

[Scope of utility model registration request]

An electronic tuner has a plurality of power supply circuits and signal input/output circuits, and includes a first substrate on which conductive electrodes of each circuit are collected, and conductive electrodes arranged parallel to the first substrate and arranged differently from the first substrate. A third substrate having a plurality of independent electrode patterns provided on both sides connected by through holes so as to electrically connect the corresponding conductive electrodes of the second substrate having the second substrate, so that the conductive electrodes on both sides are arranged differently. The substrate of the first
and a terminal structure of an electronic tuner, characterized in that it is attached at right angles to a second board.
