It is an object of the present invention to provide an oriented collagen/apatite material wherein an orientation is controlled, and a method of the oriented collagen/apatite material wherein an orientation is controlled. A method of producing an orientated collagen/apatite material according to the present invention, is characterized in that the method comprises; preparing a collagen having an orientation, seeding an osteoblast or a mesenchymal stem cell to produce and fix an apatite having an orientation similar to or almost the same as a direction of an orientation of the collagen on a surface and/or inside of the collagen. Furthermore, in a preferred embodiment of above mentioned method of producing an orientated collagen/apatite material according to the present invention, is characterized in that the osteoblast is an osteoblast like cell or an osteoblast obtained from a living organism.

The purpose of the current invention is to provide a bone strength diagnosing device and a bone strength diagnosing method capable of accurately diagnosing a bone strength of a bone. A longitudinal ultrasonic transducer and a transverse ultrasonic transducer radiate ultrasonic waves onto a bone front surface of a tibia from a predetermined angle to generate surface waves that propagate in the bone front surface in a longitudinal direction of the tibia and in a direction perpendicular to the longitudinal direction, respectively, and receive leaky waves leaking to the side of the soft tissues from the front surface waves. A speed-of-sound calculating module calculates speeds of sound of the surface waves in the transverse direction and the longitudinal direction based on a difference between course lengths of the ultrasonic waves and a difference between propagation times.
