Document Type and Number:
WIPO Patent Application WO/2022/123924
Kind Code:
A1
Abstract:
[Problem] To provide: an insulating resin composition which is capable of reducing the electrical resistance (volume resistivity) of an insulating resin, while being capable of suppressing the temperature dependence of the electrical resistance (volume resistivity) of the insulating resin; an insulating member; and an electrical device. [Solution] An insulating resin composition which contains (1) a matrix resin that contains an epoxy resin and a curing agent that cures the epoxy resin, (2) a first filler that is selected from the group consisting of silica and alumina, and (3) a second filler that is selected from the group consisting of Fe3O4 and B4C; an insulating member which is formed of a cured product of this insulating resin composition; and an electrical device which is provided with this insulating member.
