PROBLEM TO BE SOLVED: To provide a circuit board capable of maintaining a switch function for a long period of time by suppressing occurrence of deformation and chipping in a contact forming a slide part of an electric switch, and a camera including the circuit board. SOLUTION: This circuit board 29 includes an electric switch 30 having a fixed contact part 33 formed on an electrode 36 provided on the circuit board, and a movable contact part 32 mounted to another electrode 37 on the circuit board and made movable so as to come into contact with or so as not to contact with the fixed contact part 33. The fixed contact part is formed of lead free solder, and hardness of the fixed contact is higher than that in the case of the fixed contact formed of Sn-Pb based eutectic solder.
