To provide a battery pack that is less likely to be affected by vibrations, shocks and the like and has a stable characteristic, and an electric bicycle that uses the battery pack. A battery pack includes: a battery protective member having a first plate section and a second plate section which is integrally connected to both edge portions of a width direction of the first plate section and extends substantially in a direction perpendicular to both surfaces of the first plate section, wherein the flat batteries are placed on the first plate section; and a protective circuit board. A moistureproof film for the protective circuit board is formed using a plurality of film forming materials different in viscosity, hardness, and thixotropic properties. |
