"textContent": "This invention is to provide an in-vehicle interior light unit that protects a base from a thermal damage attributable to a thermal factor and reduces cost. This is achieved by adopting a general-purpose compact bulb cassette which does not have a heat shielding function although the bulb cassette still uses a heat-resistant resin as the material thereof, and the thermal deformation due to the radiant heat from a bulb is prevented by a heat shield plate integrally formed when punch-molding a bus bar, which is formed of a conductive metal member. Thus, the radiant heat from the bulb is blocked by the heat shield plate. An in-vehicle interior light unit in accordance with the present invention includes: a housing-shaped base formed of a non-heat-resistant thermoplastic resin; a bus bar integrally formed with a heat shielding plate which is mounted in the base and which rises in the vicinity of a general-purpose bulb; a bulb holder electrically connected to the bus bar; a general-purpose vertical type bulb cassette which is provided with the bulb holder and which has a socket function; a general-purpose bulb which is vertically mounted in the bulb cassette and which is electrically connected to the bulb holder; and a lens mounted on a front surface of the base.",
