An insulation pressure-resistant cylinder body of submarine (undersea) cable equipment, submarine cable equipment, and a manufacturing method are provided. The insulation pressure-resistant cylinder body includes: an installation cylinder, an insulation layer, and a pressure-resistant cylinder, disposed sequentially from inside to outside, where a first groove is opened on an outer surface of the installation cylinder, and a second groove is opened on an inner surface of the pressure-resistant cylinder, the second groove is interlaced with the first groove, and the insulation layer is closely adhered to the outer surface of the installation cylinder and the inner surface of the pressure-resistant cylinder. Through the interlaced grooves on the outer surface of the installation cylinder and on the inner surface of the pressure-resistant cylinder, the insulation layer, the installation cylinder, and the pressure-resistant cylinder are closely and integrally combined, thereby improving stability of the cylinder body.
