1. An electronic pen cartridge, configured to be mounted on a mounting part disposed in a pen-shaped casing, the electronic pen cartridge comprising:
an electronic pen main unit that includes: i) an interaction part configured to perform transmission and reception of signals with a position detecting sensor, ii) a tip part configured to be capable of protruding outside from an opening of the pen-shaped casing, and iii) a first coupling part provided at an end part opposite from the tip part in an axial center direction; and
a mounting adapter interposed between the first coupling part and the mounting part, the mounting adapter including: i) a second coupling part configured to be detachably connectable to the first coupling part of the electronic pen main unit, ii) a third coupling part configured to be detachably connectable to the mounting part of the pen-shaped casing, and iii) an elastic component that, when the second coupling part is connected to the first coupling part, exerts an elastic force to separate the mounting adapter from the electronic pen main unit in the axial center direction, wherein the elastic component is different from a writing pressure detector coil spring and serves as a shock absorber against a shock load applied along the axial center direction.
