7. A wireless power transmission device to transmit power between a first resonator and a second resonator that are disposed so as to be opposed to each other, wherein
the first resonator comprises: -
a first magnetic material core including at least one core block of magnetic material; a first winding wound around the first magnetic material core; and a first protruding portion formed so as to protrude from a part of the core block between a first end of the core block and the first winding and the second resonator comprises; a second magnetic material core including at least one core block of magnetic material; a second winding wound around the second magnetic material core; and a second protruding portion formed so as to protrude from a part of the core block of the second magnetic material core between the second winding and a first end of the core block of the second magnetic material core, the first end of the core block of the second magnetic material being on same side as a second end of the core block of the first magnetic material core, the second end being on an opposite side to the first end of the core block of the first magnetic material with respect to the first winding. - View Dependent Claims (8, 9, 10, 11, 12)

13. A resonator comprising:
-
a first magnetic material core including at least one core block of magnetic material; a first winding wound around the first magnetic material core; and a first protruding portion formed so as to protrude from a part of the core block between a first end of the core block and the first winding, wherein a first distance is defined as a distance from a center of a core block part wound by the first winding in a longitudinal direction of the core block to the first end of the core block, the first protruding portion is formed between the first end and a position apart from the first end in the longitudinal direction of the core block by one-half of the first distance.
