摘要： There is provided a heat-conducting composition capable of forming thick films in good productivity. The heat-conducting composition contains a binder and a heat-conducting filler, wherein a first viscosity thereof is 50 to 300 Pa·s as measured at a rotating speed of 10 rpm at 25° C. by using a rotational viscometer; and the ratio [second viscosity/first viscosity] of a second viscosity to the first viscosity is 3 to 8 where the second viscosity is a viscosity measured at a rotating speed of 1 rpm at 25° C. by using the rotational viscometer.
