A light emitting type capsule treatment tool for irradiating light with a specific wavelength required for photoimmunotherapy, includes a power receiving coil, a magnetic member, a light emitting member and a capsule. The power receiving coil is formed by winding a conductive wire and configured to receive electric power supplied from an external transmission antenna via a magnetic flux. The magnetic member is placed on an inner circumference of the power receiving coil. The light emitting member is configured to be supplied with electric power from the power receiving coil and to emit the light with the specific wavelength. The capsule houses the power receiving coil, the magnetic member and the light emitting member.
