A radio wave arrival angle detection device of the present invention extracts symbols and resolves the same into sub-carriers having various frequency components, for OFDM carrier waves received by a first antenna and a second antenna, respectively. The arrival angle of the carrier waves is calculated on the basis of the geometric relationship between a phase shift of the respective sub-carriers of the OFDM carrier waves received by the first antenna and the second antenna, and the arrangement of the first antenna and the second antenna.

A multilayer circuit board formed by integrally laminating a plurality of printed wiring boards in a multilayer structure so as to provide air gaps therebetween. An insulating layer is formed on each of both surfaces of a metal core substrate having through-hole forming apertures and a printed wiring layer is formed on the each insulating layer. Metal projections integrally formed on the metal core substrate serve as bonding electrodes between the adjacent wiring boards in the multilayer structure. The width of the air gap provided between the adjacent wiring boards is determined by the height of the metal projections.
