The present invention is intended to, in a configuration in which a liquid container for analysis sealed by a sealing member is penetrated by a penetrating member, prevent the sealing member from being unexpectedly broken to leak a liquid for analysis. Also, the present invention has: a container holder part that holds a liquid container for analysis; a penetrating member that penetrates a sealing member of the liquid container for analysis; a first moving mechanism that enables the penetrating member to be moved between a hole making position and a receding position; and a second moving mechanism that enables the penetrating member moved to the hole making position by the first moving mechanism to be moved toward the sealing member to a penetrating position where the penetrating member penetrates the sealing member.
