Patent ID: 7005304

Claim:
A micro-moving device comprising: an expandable element which expands and contracts by applying voltage; a flexible substrate bonded to said expandable element by an adhesive member; and a base connected to a first end of said flexible substrate; wherein said expandable element and said flexible substrate are fixed onto a fixing substrate at a second end of said flexible substrate different than said first end of said flexible substrate; wherein said expandable element comprises an external electrode connection for inputting voltage, a piezoelectric member, a first driving electrode and a second driving electrode, said first and second driving electrodes sandwiching said piezoelectric member, an insulator between said second driving electrode and said flexible substrate, said insulator covering an entire surface of said piezoelectric member, and a first lead-out electrode and a second lead-out electrode between said insulator and said flexible substrate, said first lead-out electrode being connected to said first driving electrode, and said second lead-out electrode being connected to said second driving electrode, wherein said first driving electrode has approximately the same shape as said piezoelectric member, wherein said second driving electrode is disposed above said flexible substrate via said adhesive member, wherein said flexible substrate has an electrode pad for supplying voltage to said expandable element at a position disposed on said fixing substrate, wherein a part of said first lead-out electrode acts as a first external electrode connection, and a part of said second lead-out electrode acts as a second external electrode connection, wherein said external electrode connection is connected to said electrode pad using a conductive material; and wherein said base moves by signal voltage supplied from an external source to said expandable element.
