Abstract
A tube is for use in a pump that transports a fluid by peristaltic movement and includes: a flow path that serves as a transport path of the fluid and extends in a first direction; and a body portion formed around the flow path, the body portion includes a first layer formed on the flow path and a second layer formed on the first layer, a flexural modulus of elasticity in a radial direction of the second layer is smaller than a flexural modulus of elasticity in a radial direction of the first layer, and the elastic modulus ratio R2 of the second layer is larger than the elastic modulus ratio R1 of the first layer.
