Claims

[Claims for Utility Model Registration] A light-emitting element and a light-receiving element formed between the light-emitting element and the light-receiving element of a photo/electrical conversion module having a structure in which the light-emitting element and the light-receiving element are sealed inside a transparent resin mold body. A light/electrical conversion module comprising: a light shielding member mounting groove; and a light shielding member that is attached to the light shielding member mounting groove and optically defines the light/electrical conversion module on a light emitting element side and a light receiving element side. Light-shielding structure.
