Charging pad

A charging pad comprising:

• a side surface on which a charged terminal device is to be placed face to face, the side surface comprising:
• a protruding flat surface portion raised from a peripheral edge portion of the protruding flat surface portion that is inset from a peripheral edge portion of the side surface;
• a power transfer coil incorporated in a raised region of the protruding flat surface portion;
• and
• a holding mechanism allowing the charged terminal device to be held to a predetermined position with respect to the power transfer coil, wherein:
• the outer peripheral edge of the side surface is substantially rectangular in shape and includes one side that is rounded with a greater radius between the side surface and an intersecting end surface of the charging pad than radii of intersection between the other three sides of the outer peripheral edge of the side surface and respective end surfaces of the charging pad, and
• the charging pad further comprises a light emitting unit disposed at the peripheral edge portion of the side surface except for along the one side that is rounded with a greater radius between the side surface and the intersecting end surface of the charging pad, wherein the light emitting unit extends part way down along each of opposing end surfaces of the charging pad at each of the opposing ends of the one side so as to be visible when the charged terminal device is placed on the protruding flat surface portion of the side surface.
