The present invention relates to an anisotropic conductive film and a method for manufacturing same, and a bonding structure and an ultrasonic biometric identification apparatus. The anisotropic conductive film comprises first conductive particles and second conductive particles, wherein the particle size of the first conductive particles is less than the particle size of the second conductive particles, and the ratio of the number of the first conductive particles to the number of the second conductive particles is (3-8):1. The anisotropic conductive film is applicable to pins made of different materials, and is particularly applicable to a bonding structure where a pin made of a relatively hard material and a pin made of a relatively loose material exist at the same time, thereby ensuring that the anisotropic conductive film has a relatively low conduction impedance and excellent conduction stability on both of the two materials.
