PROBLEM TO BE SOLVED: To suppress defects in a membrane electrode junction manufacturing process.

SOLUTION: The technology forms seal member intake through-holes 62a, 62b on a membrane electrode junction prior to injection molding in addition to manifold holes 16a to 16f. When placing the membrane electrode junction in a mold for injection molding, the seal member intake hole 62a is positioned within a cavity 44a. When seal members are supplied from an intake 42 in a portion where the manifold hole 16a is formed, the seal members fed into the upper mold 40a within the cavity 44a are also fed into the lower mold 40b through the seal member intake hole 62a to reduce a gap between the seal member quantities in the upper mold 40a and lower mold 40b.

【課題】膜電極接合体の製造過程における不良の発生を抑制する。
【解決手段】射出成形前の膜電極接合体に対して、マニホールド孔16a〜16fとは別に、貫通孔であるシール部材流入孔62a、62bを形成する。射出成形のために金型内に膜電極接合体を配置する際に、シール部材流入孔62aをキャビティ44a内に配置する。マニホールド孔16a形成部位にある供給口42からシール部材が供給されると、キャビティ44a内において、上型40a側に流入したシール部材はシール部材流入孔62aを通り、下型40b側にも流入し、上型40aと下型40bへのシール部材供給量の不均等を軽減する。
