1. A power reception device, comprising:
- a vehicle-side resonant portion mounted on a vehicle and resonating, through an electromagnetic field, with a facility-side resonant portion provided in an external facility; and
a vehicle-side support including a first support member supporting said vehicle-side resonant portion, and a second support member spaced apart from said vehicle-side resonant portion and supporting said first support member, whereina dielectric tangent of said first support member is smaller than a dielectric tangent of said second support member.
