PROBLEM TO BE SOLVED: To provide an eyeball biological information collection device, which enables collection of a fluctuation in the eyeball biological information with constant measurement timing.SOLUTION: An eyeball biological information collection device includes: an ultrasonic sensor part 10 which transmits ultrasonic waves to a subject's eyeball and which receives reflected waves reflected from the eyeball； a close contact part which brings the ultrasonic sensor part 10 into close contact with the subject's eyelid in use； a data calculation part 40 which calculates intraocular pressure on the basis of detection data detected by the ultrasonic sensor part； a data storage part 50 which stores the detection data detected by the ultrasonic sensor part 10 and calculation data calculated by the data calculation part 40； a timer part 65 which sets measurement timing and a measurement interval on the basis of time information； and a control part 60 which controls the ultrasonic sensor part 10, the data calculation part 40, the data storage part 50 and the timer part 65. The intraocular pressure is obtained by the measurement timing and the measurement interval, which are set by the timer part 65.
