PROBLEM TO BE SOLVED: To provide a synthetic resin pipe capable of exhibiting an insect proof effect with respect to plural kinds of insects.SOLUTION: A synthetic resin pipe 1 comprises: a first insect proof layer 3a including a first insect proof component and continuously formed in a longitudinal direction of the pipe 1; and a second insect proof layer 3b including a second insect proof component and intermittently formed on an inner surface of the first insect proof layer 3a in the longitudinal direction of the pipe 1. Of the first insect proof layer 3a, a portion exposed to inside of the pipe 1 is a first insect proof part 2a, and the second insect proof layer 3b is a second insect proof part 2b. The pipe 1 is configured so that, the first insect proof part 2a and the second insect proof part 2b are repeatedly arranged and exposed in the longitudinal direction on the inside of the pipe 1.SELECTED DRAWING: Figure 1 |
