The invention discloses a wood pen holder and a manufacturing method thereof, which relates to a manufacturing method of a writing tool, belonging to the technical field of miscellaneous wood molding and 
processing. The wood pen holder is characterized by comprising the following components in percentage by weight: 50-80 percent of hard miscellaneous wood 
raw material, 4-15 percent of various 
sawdust, 5-10 percent of various shavings, 2-5 percent of various wood dust, 4-10 percent of polyhydroxyalkanoate, 3-5 percent of 
starch, 1-7 percent of cross-linking agent and 1-3 percent of 
plasticizer. The invention has the advantages that a large quantity of waste forest harvesting trees and miscellaneous wood are used as main production raw materials, so that the limits of 
raw material tree varieties are avoided, the tree variety raw materials can be flexibly collocated so as to meet the requirement on low cost production; the production cost not only can be reduced, but also the 
mechanical strength of produced wood plates can be guaranteed to conform to the 
wood panel standard of the Sweden; and meanwhile, after the forest harvesting trees and miscellaneous wood are utilized, a greater economic benefit not only can be directly generated by 
manufacturing enterprises, but also forest fires and pest and 
disease damages can be reduced, which is helpful to the ecological cycle.
