A lamp device having a lamp unit, a radar unit that radiates an electromagnetic wave, and a transparent cover, the lamp device comprising:
- a shielding member which is placed between the transparent cover and an electromagnetic wave radiation surface of the radar unit, covers at least a part of a front surface of the radar unit, and is made of a foamed resin;
- wherein a thickness TK of an electromagnetic wave radiation surface correspondence area that corresponds to the electromagnetic wave radiation surface of the transparent cover is set such that a reflection loss of the electromagnetic wave incident upon the electromagnetic wave radiation surface correspondence area of the transparent cover is −10 dB or less,
- a thickness TG of the shielding member is set such that a reflection loss of the electromagnetic wave incident upon the shielding member is −10 dB or less, and
- an interval C1 between the electromagnetic wave radiation surface correspondence area and the shielding member is set such that the reflection loss of the electromagnetic wave incident upon the electromagnetic wave radiation surface correspondence area and the shielding member is −10 dB or less.
