PROBLEM TO BE SOLVED: To provide a technology for improving the position accuracy between a light source and an optical member.SOLUTION: A lamp fitting unit includes: a circuit board 36 on which a semiconductor light emitting element 38 is mounted; and a reflection member 82 fixed to the circuit board 36. In the circuit board 36, a pin 100 for an optical member, which is made of a material different from a base material of the circuit board 36, is provided on a placement surface 36g on which the reflection member 82 is placed. In the reflection member 82, a round hole 90a is provided at a position corresponding to the pin 100 for the optical member. The pin 100 for the optical member is inserted into the round hole 90a thereby positioning the reflection member 82 relative to the circuit board 36. |
