摘要： An ultrasonic inspection apparatus includes: an acquisition unit acquiring a signal indicating a fundamental wave and a second harmonic of an ultrasonic wave, which are obtained by the ultrasonic wave being scanned over an inspection object through a medium, at each scanning position; a calculation unit calculating a value obtained by dividing a second harmonic amplitude by a square of a fundamental wave amplitude, at each scanning position; and an output unit outputting information on a defect of the inspection object, based on the value obtained by dividing the second harmonic amplitude by the square of the fundamental wave amplitude.

摘要： The manufacturing method includes surface treatment and bonding. In the surface treatment, micro-order or nano-order asperities are formed on a surface of the metallic member. The bonding includes directly bonding the metallic member and the fiber-reinforced resin member by repeatedly bonding a melted portion of the fiber-reinforced resin member to the surface of the metallic member while partially melting the fiber-reinforced resin member, the metallic member having the asperities formed by the surface treatment.
