A polyamide resin composition which can improve heat resistance and water absorbency while suppressing the deterioration of processability is provided. The LWC has a shift section where the pipe is shifted from the m-th coil layer to the -th coil layer on a bottom surface thereof when the LWC is disposed on a mount surface. These nodes constitute the key elements of a wireless network that would be deployed and controlled by a wireless network operator. The substrate includes a top side, a bottom side, and a conductive interface. In one embodiment, the film is a concentrated mouthwash which reacts when water is added to the container, such as a disposable cup, to reconstitute the mouthwash at a desired strength.
