Polyethylene powder with excellent solubility and dispersibility, and high-quality (for example, uniform, low undissolved material, excellent dimensional accuracy) molded product (for example, microporous film, high-strength fiber, and porous) containing the same. A quality sintered body) is intended to be provided. The ultimate viscosity [η] measured in decalin at 135 ° C. is 2.0 dl / g or more and less than 20.0 dl / g, and is 120 with respect to the specific surface area A measured by the BET method before heating at 120 ° C. for 5 hours. A polyethylene powder having a reduction rate of specific surface area B ((AB) / A × 100) measured by the BET method after heating at ° C. for 5 hours of 0.1% or more and less than 35%. |
