Abstract:
A thermal conductor includes a plurality of thermal conducting portions; and joint portions made of a material having flexibility and configured to join the respective thermal conducting portions with each other, having voids where neither the thermal conducting portion nor the joint portion is present, and satisfying a condition of 0.5≤[(S1−S0)/S0]×100≤20 when an area of the thermal conductor in a planar view in a first direction is expressed by S0 [cm2] and an area of the thermal conductor in the planar view in the first direction in a pressed state that the thermal conductor is pressed by 0.2 MPa in the first direction is expressed by S1 [cm2]. Accordingly, the thermal conductor satisfies both ensuring adhesiveness to a member in contact with the thermal conductor in use and suppressing excessive deformation of the thermal conductor in a compressed state.
