To provide a microwave circuit board which can be mounted with an imaging device without causing a large deformation and in which an optical characteristic of a light transmission part in an opening hole is not degraded.
The microwave circuit board 6 is disclosed, which is provided with at one side an imaging device mount part 2 for mounting the imaging device 1 and a lens support part 4 for supporting a lens 3 at the side opposite from the imaging device mount part 2, and wherein the opening hole 5 open to the imaging device mount part 2 and the lens support part 4 is formed. The opening hole 5 is provided with the light transmission part 7 formed by integrally forming an optical transparent material to clog the inside of the opening hole 5. Clogging the opening hole 5 with the light transmission part 7 can reinforce the part of the opening hole 5. Further, the optical transparent material is integrally formed in the opening hole 5 to be able to form the light transmission part 7 after the microwave circuit board 6 is formed, so that a forming pressure and a stress of curing contraction caused when the microwave circuit board 6 is formed do not act on the light transmission part 7.
