There is provided a method for producing a force sensor including: a force sensor chip; and an attenuator, in which the force sensor chip and the attenuator are joined at joint portions with a glass layer sandwiched therebetween. The method includes: a film forming step in which a glass film as the glass layer is formed on regions of the attenuator containing the joint portions or on regions of the force sensor chip containing the joint portions; and an anodic bonding step in which the force sensor chip and the attenuator are stacked as a stacked body in close contact with each other at the joint portions, and the glass film and the force sensor chip, or the glass film and the attenuator, are joined.
