Abstract

A power reception device comprising a coil (22) and a core (21) around which the coil (22) is wound. The core (21) includes: a shaft section (33) that extends in the extension direction of a winding shaft (O1) and around which the coil (22) is wound; and magnetic pole sections (34a , 34b) formed on at least one end section of the shaft section (33) and extending in the intersecting direction intersecting with the extension direction of the winding shaft (O1). The width of the shaft section (33) in the intersecting direction is less than the length of the magnetic pole sections (34a , 34b) in the intersecting direction, and is formed such that a first center section positioned at the center of the magnetic pole sections (34a , 34b) in the intersecting direction and a second center section positioned at the center of the shaft section (33) in the intersecting direction are mutually out of alignment in the intersecting direction.
