A production method of an article for water sports such as a surfboard with a hollow structure achieves a wide range of selections for users. The article is established with sufficient strength and durability, and is capable of achieving low cost and short delivery time. The article is configured by an outer shell having a hollow structure for forming an outer shape of a main body of the surfboard, a partition wall arranged within an internal space of the outer shell for connecting inner surfaces facing one another in said internal space, sectioned spaces separated and sealed by said partition wall and the inner surfaces of the outer shell, and a vent hole formed on said partition wall so that the sectioned spaces adjacent to one another can properly communicate with one another. |
