<p>A plurality of tubular members are incorporated in a wind instrument for forming an air passage, and each of the tubular members (14) has a tubular portion (14a) and a guide portion (14b) larger in diameter than the tubular portion and rounding therefrom for forming a hollow space (14c) open to the inner space (14d) of the tubular portion, thereby preventing the external appearance of the wind instrument from residual electrolyte confined during a plating bath. <IMAGE></p> |
