Abstract:
1. A force sensor comprising: a force sensor chip comprising: an action portion to which an external force is transmitted, a connecting portion which is adjacent to the action portion and on which strain resistive elements are disposed, and a support portion for supporting the action portion and the connecting portion, the force sensor chip for detecting an external force by the strain resistive elements; an attenuator comprising: an input portion to which the external force is input, a fixing portion for fixing the force sensor chip, and a transmission portion for attenuating the external force and transmitting the attenuated external force to the action portion; a first glass member disposed between the action portion and the transmission portion and a second glass member disposed between the support portion and the fixing portion, through which first and second glass members the force sensor chip and the attenuator are joined; and a joint member for joining the first glass member and the second glass member together as a single member.
