To provide a wind instrument made of bamboo charcoal and its manufacturing method in which mechanical strength of a bamboo charcoal pipe is increased by impregnating a surface texture part of the bamboo charcoal pipe with a synthetic resin agent and by using bamboo charcoal powder as an aggregate of an applied layer and further peculiar tone colors of the bamboo charcoal pipe can be displayed.

A coating material 15 produced by kneading the synthetic resin agent 12 having impregnating ability and hardenability by drying with the particulate bamboo charcoal powder 13 is applied on an inner peripheral wall 11 of the carbonized bamboo charcoal pipe 1a to manufacture the wind instrument made of bamboo charcoal. Further in the manufacturing method of the wind instrument made of bamboo charcoal, a bamboo raw material 1' in which nodes are removed while reserving a node base part 16 is accommodated in an auxiliary bamboo pipe 17 in a state surrounded with a carbonizable carbonization buffering member 19 such as newspaper and then the bamboo raw material 1' is carbonized via the auxiliary bamboo pipe 17 and the carbonization buffering member 19 in a carbonization kiln 20 to manufacture the bamboo charcoal pipe 1a.
