Abstract

A radio wave transmissive member, including an outer layer, an intermediate layer and an inner layer in this order, the radio wave transmissive member having a region in which X1, as a total thickness of the outer layer and the inner layer in a transmission direction of a radio wave, satisfies the following Formula (1) and Formula (3), and X2, as a thickness of the intermediate layer in a transmission direction of the radio wave, satisfies the following Formula (2) and Formula (3): Z−0.6mm≤X1≤Z+0.6mmZ−0.3mm≤X2≤Z+0.3mmZ=λ÷√εr×0.5×Y wherein, in the Formulas, λ represents a wavelength in vacuum of the radio wave, ε_r represents a relative permittivity of each layer at a frequency of the radio wave, and Y represents an integer of 1 or more.
