Zusammenfassung:	Provided is a glass strand that, when mixed with mortar, is less likely to decrease the fluidity of the mortar and can 5 effectively increase the mechanical strength of a cementitious material. A glass strand includes: a plurality of glass filaments containing 12% by mass or more ZrO2 and 10% by mass or more R2O (where R represents at least one selected from Li, Na, and K); and a coating covering surfaces of the glass filaments, 10 wherein the coating contains polyvinyl acetate resin and polyether-based urethane resin, and wherein a content of the polyether-based urethane resin in the coating is, in solid content ratio, not less than 10% by mass and not more than 90% by mass.
