Abstract
A ball lens assembly constructed of a lens holder formed with a press-fit hole having a circular section and a ball lens press-fitted with the press-fit hole of the lens holder. The lens holder is formed by sintering stainless steel powder. As the lens holder is formed by sintering, a force for press-fitting the ball lens into the lens holder can be suppressed to thereby effectively prevent breakage of the ball lens.
