To suppress exfoliation of the conductor pattern of a through-hole formed on an end surface of a control circuit board for a camera.
The control circuit board 0 for a camera comprises a wiring base member 4 on which a wiring conductor pattern is formed, optical distance measuring parts 1 assembled on the wiring base member 4 for measuring the distance to an object to be photographed, and circuits 41, 42 assembled on the wiring base member 4 and mutually connected through the intermediary of the conductor pattern for controlling respective parts of a camera. The wiring base member 4 includes an end surface 43 and a flat plane 44 in succession to the end surface 43. In the end surface 43, there is formed a through-hole 45 along a peripheral wall of which a soldering first conductor pattern adheres. On the flat plane 44, there is formed a second conductor pattern constituting a land 47 in succession to the first conductor pattern. The size of the width of the land 47 is larger than the size of the diameter of the through-hole 45. The center of the through-hole 45 is located for inside from an external contour line of the end surface 43.
