Provided is a thermally conductive molded resin article that can be inexpensively mass-produced and that exhibits a low thermal resistance value as a result of reducing internal thermal resistance by high filling and reducing interfacial thermal resistance by improving cutting precision. The thermally conductive molded resin article is characterized by comprising a resin and thermally conductive fillers including a first thermally conductive filler and a second thermally conductive filler having a smaller particle size than the first thermally conductive filler. The thermally conductive molded resin article is also characterized in that: the first thermally conductive filler has an aspect ratio of 10 or more and is oriented approximately in the thickness direction of the thermally conductive molded resin article; the resin is a silicone resin, an acrylic rubber, or a fluororubber; and the second thermally conductive filler has a thermal conductivity surpassing 5 W/mK.

Thermally conductive molded resin article

The present invention provides an optically clear adhesive sheet that has excellent flexibility and prevents delay bubbles in high temperature and high humidity environments. The optically clear adhesive sheet of the present invention sequentially includes a first surface-adhesive layer, an intermediate adhesive layer, and a second surface-adhesive layer. The first surface-adhesive layer and the second surface-adhesive layer each have a higher storage elastic modulus at 85&#xb0; C. than the intermediate adhesive layer. The first surface-adhesive layer and the second surface-adhesive layer each have a storage elastic modulus at 85&#xb0; C. of 3.0&#xd7;10Pa or higher and 30.0&#xd7;10Pa or lower. The intermediate adhesive layer has a storage elastic modulus at 85&#xb0; C. of 1.0&#xd7;10Pa or higher and 15.0&#xd7;10Pa or lower. The intermediate adhesive layer contains polyurethane.
