Abstract:
An electronic device of the present invention includes a first substrate provided with a thin film active element, having a thickness of 200 μm or lower, and a second substrate formed with a high thermal conductivity portion. The second substrate is applied to one surface of the two surfaces of the first substrate, i.e., the surface being the side other than the side that formed with the thin film active element. The thin film active element has a maximum power consumption of 0.01 to 1 mW. The high thermal conductivity portion is a region that corresponds to the position of the thin film active element and whose thermal conductivity falls within the range from 0.1 to 4 W/cm·deg.
