A medical power supply includes a medical instrument and a guide tube. The power receiving member is arranged radially outside the insertion portion, and when the insertion portion is inserted into the guide tube to a predetermined length such that the power transmitting member and the power receiving member are close to each other, a power transmitting side proximal end surface of the power transmitting member and a power receiving side distal end surface of the power receiving member face each other in an axial direction of the insertion portion and are in a positional relationship such that wireless power supply is possible.
