PROBLEM TO BE SOLVED: To provide a light source equipment which enables a series combination of light emitting element chips and has superior heat radiation effect and uses a small number of item parts. SOLUTION: A metal substrate 1 is divided into separate metal sections 4 by an insulating layer 2, formed on a rear face of the substrate 1 and insulating layers formed in the vertical directions. On the surface of each metal section 4 of the metal substrate 1, an LED chip 5 is disposed directly, with one pole electrically connected to the metal section 4 and the other pole bonded to an adjacent metal section 4 by a metal wire 6. The LED chips 5, with each disposed on each metal section 4, are serially connected with each other. |
