1. An energy treatment instrument comprising:
- a held unit which has a longitudinal axis, and which is capable of being held, the held unit including;
a case main body which extends along the longitudinal axis; and
a stationary handle which extends from the case main body in an extension direction crossing the longitudinal axis;
an end effector exposed outside of the held unit, and configured to contact to a biological tissue;
a magnetic member including a magnetic material;
an electric-receiver-side resonator including an electric receiver coil which has a coil axis that is located distant from the magnetic member, and a capacitor, an inductance of the electric receiver coil and a capacitance of the capacitor being set in a state in which the electric-receiver-side resonator resonates at a same resonance frequency as an electric-supplier-side resonator including an electric supplier coil, the electric-receiver-side resonator being configured to resonate at the resonance frequency so that electric power for thermally denaturing the biological tissue contacted by the end effector is supplied from the electric supplier coil to the electric receiver coil during a treatment; and
an energy generator configured to generate energy for use in the treatment, by using the electric power supplied to the electric receiver coil,wherein the magnetic member extends along the longitudinal axis of the held unit, andthe coil axis of the electric receiver coil does not intersect the longitudinal axis of the held unit when the held unit is viewed from each of one side and the other side of a width direction of the held unit which is perpendicular to the longitudinal axis and the extension direction of the stationary handle.

Abstract
An energy treatment instrument includes a held unit capable of being held, and an electric-receiver-side resonator including an electric receiver coil wound around a coil axis, and resonating at the same resonance frequency as an electric-supplier-side resonator, thereby electric power being supplied from an electric supplier coil to the electric receiver coil. The energy treatment instrument includes an energy generator generating energy for use in a treatment by using the electric power supplied to the electric receiver coil, and a magnetic member including a magnetic material and located distant from the coil axis of the electric receiver coil.
