The resin material according to the present invention contains first inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.90 or less, second inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.95 or more, third inorganic particles having an average aspect ratio of more than 2, and a binder resin.
Claims14
A resin material comprising:
- first inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.90 or less;
- second inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.95 or more;
- third inorganic particles having an average aspect ratio of more than 2;
- and
- a binder resin,
- the content of the first inorganic particles in 100% by volume of the resin material being 0.5% by volume or more and 55% by volume or less,
- the content of the second inorganic particles in 100% by volume of the resin material being 0.5% by volume or more and 55% by volume or less, and
- the content of the third inorganic particles in 100% by volume of the resin material being 25% by volume or more and 65% by volume or less.
A laminate comprising:
- a thermal conductor;
- an insulating layer laminated on one surface of the thermal conductor;
- and
- a conductive layer laminated on a surface of the insulating layer opposite to the thermal conductor,
- the insulating layer containing first inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.90 or less, second inorganic particles having an average aspect ratio of 2 or less and an average circularity of 0.95 or more, third inorganic particles having an average aspect ratio of more than 2, and a binder resin,
- the content of the first inorganic particles in 100% by volume of the insulating layer being 0.5% by volume or more and 55% by volume or less,
- the content of the second inorganic particles in 100% by volume of the insulating layer being 0.5% by volume or more and 55% by volume or less, and
- the content of the third inorganic particles in 100% by volume of the insulating layer being 25% by volume or more and 65% by volume or less.
