PROBLEM TO BE SOLVED: To efficiently prevent dirt from sticking onto a condenser lens, while satisfying the condensing performance of the condenser lens and protectivity, concerning a light source connector for an endoscope, which is connected to a light source device and includes the condenser lens where light from the light source device is made incident. SOLUTION: The light incident surface of the condenser lens arranged in the light source connector is formed as a projected surface which satisfies R/d≥1 when R is the curvature radius of the light incident surface and d is the outer diameter of the condenser lens.
