Claim Text:
1. A polyamide comprising: a unit comprising at least one (a) alicyclic dicarboxylic acid; and a unit comprising a (b) diamine having 8 or more carbon atoms, wherein the polyamide satisfies the following conditions (1) and (2): (1) a sulfuric acid relative viscosity ηr at 25° C. is 2.3 or more; and (2) Mw (weight average molecular weight)/Mn (number average molecular weight) is 3.0 or less; wherein a ratio (η*1/η*100) of a shear viscosity (η*1) at an angular velocity of 1 rad/s to a shear viscosity (η*100) at an angular velocity of 100 rad/s is 3 or less.
