The internal mold resin is a cured product of a composition having an epoxy resin and a curing agent, and is a resin having a light transmission property. Additionally, the internal mold resin MRI contains an aromatic ring and an alicyclic compound. By thus lowering the ratio of an aromatic ring in the epoxy resin, deterioration of the resin can be suppressed. Thereby, a decrease in the light transmission property of the epoxy resin cured product can be suppressed, and degradation of the transmission performance for an optical signal can be reduced."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical coupling device, manufacturing method thereof, and power conversion system","description":"In order to improve properties, an optical coupling device has a potting resin and an internal mold resin between a light emitting element and a light receiving element.
