Power transmitting apparatus, power receiving apparatus, and power transmission system

A power transmitting apparatus (101) has a power transmitting apparatus side active electrode (12) provided within the casing thereof along a seat (10D). A power transmitting apparatus side passive electrode (11) is exposed on a backrest (10B). A power receiving apparatus (201) has a power receiving apparatus side active electrode (22) formed along the bottom surface thereof. A power receiving apparatus side passive electrode (21) is formed on the outer surface of the casing (20) of the power receiving apparatus (201). By mounting the power receiving apparatus (201) on a mounting portion of the power transmitting apparatus (101), the power receiving apparatus side active electrode (22) faces the power transmitting apparatus side active electrode (12) with a dielectric layer therebetween, and the power receiving apparatus side passive electrode (21) is directly electrically connected to the power transmitting apparatus side passive electrode (11).
