PROBLEM TO BE SOLVED: To provide a low-substituted hydroxypropyl cellulose having good binding property, capping prevention performance and disintegration property. SOLUTION: The content of hydroxypropoxy group is 5 to 16% by mass, and all particles are classified into fine particles, spherical particles, long fibrous particles, and short fibrous particles by a dynamic image analysis method. In the case, a low-substituted hydroxypropyl cellulose having a body integration ratio of the long fibrous particles with respect to all the particles of more than 50.0% is provided, and a solid preparation containing at least the low-substituted hydroxypropyl cellulose is provided.
