Abstract: A curable resin composition includes a main agent, an amine-based curing agent, and a phenol-based curing agent. The main agent includes at least one of a maleimide compound and an epoxy compound. The amine-based curing agent is made of aromatic polyamine. The phenol-based curing agent is made of phenols that has a phenolic OH equivalent of equal to or less than 90 and has a softening point or a melting point of equal to or lower than 100° C.

Abstract: A curable polyurethane type resin composition which is applicable for a sealing material for an electrical device used in a vehicle, enhances a hydrolysis resistance of a cured substance and can suppress a decrease in physical properties in high temperature and high moisture environments. The curable polyurethane type resin composition contains castor oil-type polyol, polyisocyanate, and epoxidized acrylic polymer. The electrical device has electrical components covered with a sealing material consisting of a cured substance of the curable polyurethane-type resin composition.
