Producing method of part with adhesive, and part with adhesive

A producing method of a part with adhesive in which a plurality of parts are placed on one base material, the base material itself configures the parts, and the parts to which the adhesive adheres is produced by punching the parts from the base material, wherein the producing method includes:

• a printing process of applying, by printing, the adhesive which does not express adherence property on at least a portion of a surface forming the part from one of surfaces of the base material;
• an ultraviolet irradiation process of irradiating, after the printing process, the base material with ultraviolet to make the adhesive express adherence property;
• a release paper pasting process of pasting release paper on the one surface of the base material;
• and
• an outward form pressing process of punching an outer form of the part,
• wherein the base material is a PET film, and the part is an encoder, and
• a hole is formed in the part by punching working before the printing process.

• and
• an outward form pressing process of punching an outer form of the part, wherein the base material is a translucent PET film, and the part is a rotary encoder,
• the producing method further includes:
• a slit pattern process of forming a light-blocking pattern in the part, and
• an inner-diameter punching working process of forming a center hole in the part, a motor shaft being inserted into the center hole, and,
• the slit pattern process and the inner-diameter punching working process are carried out before the printing process.
