Liquid discharge apparatus, and driving circuit provided in liquid discharge apparatus

A driving circuit provided in a liquid discharge apparatus that includes:

• a frame;
• a substrate that is fixed to the frame and has a first surface and a second surface;
• a heat conductive sheet;
• and
• a head unit that is driven by a driving signal and is capable of discharging liquid,
• the driving circuit comprising:
• a first circuit that is provided on the first surface;
• and
• a second circuit that is provided on the second surface,
• wherein the first circuit includes a driving signal generation circuit that generates the driving signal using a first transistor and a second transistor,
• the heat conductive sheet is in contact with the frame, the first surface, the first transistor, and the second transistor, and
• a distance between a portion of the first circuit farthest from the first surface and the first surface is shorter than a distance between a portion of the second circuit farthest from the second surface and the second surface.
